Immunoglobulin supergene family

Main article: Immunoglobulin supergene family

The immunoglobulin supergene family is "the group of proteins that have immunoglobulin-like domains, including histocompatibility antigens, the T-cell antigen receptor, poly-IgR, and other proteins involved in the vertebrate immune response (17)."[1]

Alpha-1-B glycoprotein variants

Gene ID: 1 A1BG alpha-1-B glycoprotein on 19q13.43: "The protein encoded by this gene is a plasma glycoprotein of unknown function. The protein shows sequence similarity to the variable regions of some immunoglobulin supergene family member proteins."[2]

"𝛂1B-glycoprotein(𝛂1B) [...] consists of a single polypeptide chain N-linked to four glucosamine oligosaccharides. The polypeptide has five intrachain disulfide bonds and contains 474 amino acid residues. [...] 𝛂1B exhibits internal duplication and consists of five repeating structural domains, each containing about 95 amino acids and one disulfide bond. [...] several domains of 𝛂1B, especially the third, show statistically significant homology to variable regions of certain immunoglobulin light and heavy chains. 𝛂1B [...] exhibits sequence similarity to other members of the immunoglobulin supergene family such as the receptor for transepithelial transport of IgA and IgM and the secretory component of human IgA."[1]

"Some of the domains of 𝛂1B show significant homology to variable (V) and constant (C) regions of certain immunoglobulins. Likewise, there is statistically significant homology between 𝛂1B and the secretory component (SC) of human IgA (15) and also with the extracellular portion of the rabbit receptor for transepithelial transport of polymeric immunoglobulins (IgA and IgM). Mostov et al. (16) have called the later protein the poly-Ig receptor or poly-IgR and have shown that it is the precursor of SC."[1]

"𝛂1B-glycoprotein(𝛂1B) [...] consists of a single polypeptide chain N-linked to four glucosamine oligosaccharides. The polypeptide has five intrachain disulfide bonds and contains 474 amino acid residues. [...] 𝛂1B exhibits internal duplication and consists of five repeating structural domains, each containing about 95 amino acids and one disulfide bond. [...] several domains of 𝛂1B, especially the third, show statistically significant homology to variable regions of certain immunoglobulin light and heavy chains. 𝛂1B [...] exhibits sequence similarity to other members of the immunoglobulin supergene family such as the receptor for transepithelial transport of IgA and IgM and the secretory component of human IgA."[1]

A1BG contains the immunoglobulin domain: cl11960 and three immunoglobulin-like domains: pfam13895, cd05751 and smart00410.

"Immunoglobulin (Ig) domain [cl11960] found in the Ig superfamily. The Ig superfamily is a heterogenous group of proteins, built on a common fold comprised of a sandwich of two beta sheets. Members of this group are components of immunoglobulin, neuroglia, cell surface glycoproteins, such as, T-cell receptors, CD2, CD4, CD8, and membrane glycoproteins, such as, butyrophilin and chondroitin sulfate proteoglycan core protein. A predominant feature of most Ig domains is a disulfide bridge connecting the two beta-sheets with a tryptophan residue packed against the disulfide bond."[3]

"This domain [pfam13895] contains immunoglobulin-like domains."[4]

"Ig1_LILR_KIR_like: [cd05751] domain similar to the first immunoglobulin (Ig)-like domain found in Leukocyte Ig-like receptors (LILRs) and Natural killer inhibitory receptors (KIRs). This group includes LILRB1 (or LIR-1), LILRA5 (or LIR9), an activating natural cytotoxicity receptor NKp46, the immune-type receptor glycoprotein VI (GPVI), and the IgA-specific receptor Fc-alphaRI (or CD89). LILRs are a family of immunoreceptors expressed on expressed on T and B cells, on monocytes, dendritic cells, and subgroups of natural killer (NK) cells. The human LILR family contains nine proteins (LILRA1-3,and 5, and LILRB1-5). From functional assays, and as the cytoplasmic domains of various LILRs, for example LILRB1 (LIR-1), LILRB2 (LIR-2), and LILRB3 (LIR-3) contain immunoreceptor tyrosine-based inhibitory motifs (ITIMs) it is thought that LIR proteins are inhibitory receptors. Of the eight LIR family proteins, only LIR-1 (LILRB1), and LIR-2 (LILRB2), show detectable binding to class I MHC molecules; ligands for the other members have yet to be determined. The extracellular portions of the different LIR proteins contain different numbers of Ig-like domains for example, four in the case of LILRB1 (LIR-1), and LILRB2 (LIR-2), and two in the case of LILRB4 (LIR-5). The activating natural cytotoxicity receptor NKp46 is expressed in natural killer cells, and is organized as an extracellular portion having two Ig-like extracellular domains, a transmembrane domain, and a small cytoplasmic portion. GPVI, which also contains two Ig-like domains, participates in the processes of collagen-mediated platelet activation and arterial thrombus formation. Fc-alphaRI is expressed on monocytes, eosinophils, neutrophils and macrophages; it mediates IgA-induced immune effector responses such as phagocytosis, antibody-dependent cell-mediated cytotoxicity and respiratory burst."[5]

"IG domains [smart00410] that cannot be classified into one of IGv1, IGc1, IGc2, IG."[6]

Genes having immunoglobulin like domain smart00410

Gene ID: 177 see Major histocompatibility complex class III gene family.

Gene ID: 2260 is FGFR1 fibroblast growth factor receptor 1: "The protein encoded by this gene is a member of the fibroblast growth factor receptor (FGFR) family, where amino acid sequence is highly conserved between members and throughout evolution. FGFR family members differ from one another in their ligand affinities and tissue distribution. A full-length representative protein consists of an extracellular region, composed of three immunoglobulin-like domains, a single hydrophobic membrane-spanning segment and a cytoplasmic tyrosine kinase domain. The extracellular portion of the protein interacts with fibroblast growth factors, setting in motion a cascade of downstream signals, ultimately influencing mitogenesis and differentiation. This particular family member binds both acidic and basic fibroblast growth factors and is involved in limb induction. Mutations in this gene have been associated with Pfeiffer syndrome, Jackson-Weiss syndrome, Antley-Bixler syndrome, osteoglophonic dysplasia, and autosomal dominant Kallmann syndrome 2. Chromosomal aberrations involving this gene are associated with stem cell myeloproliferative disorder and stem cell leukemia lymphoma syndrome. Alternatively spliced variants which encode different protein isoforms have been described; however, not all variants have been fully characterized."[7]

Gene ID: 2261 is FGFR3 fibroblast growth factor receptor 3 on 4p16.3: "This gene encodes a member of the fibroblast growth factor receptor (FGFR) family, with its amino acid sequence being highly conserved between members and among divergent species. FGFR family members differ from one another in their ligand affinities and tissue distribution. A full-length representative protein would consist of an extracellular region, composed of three immunoglobulin-like domains, a single hydrophobic membrane-spanning segment and a cytoplasmic tyrosine kinase domain. The extracellular portion of the protein interacts with fibroblast growth factors, setting in motion a cascade of downstream signals, ultimately influencing mitogenesis and differentiation. This particular family member binds acidic and basic fibroblast growth hormone and plays a role in bone development and maintenance. Mutations in this gene lead to craniosynostosis and multiple types of skeletal dysplasia."[8]

Gene ID: 3815 is KIT KIT proto-oncogene, receptor tyrosine kinase on 4q12: "This gene encodes a receptor tyrosine kinase. This gene was initially identified as a homolog of the feline sarcoma viral oncogene v-kit and is often referred to as proto-oncogene c-Kit. The canonical form of this glycosylated transmembrane protein has an N-terminal extracellular region with five immunoglobulin-like domains, a transmembrane region, and an intracellular tyrosine kinase domain at the C-terminus. Upon activation by its cytokine ligand, stem cell factor (SCF), this protein phosphorylates multiple intracellular proteins that play a role in in the proliferation, differentiation, migration and apoptosis of many cell types and thereby plays an important role in hematopoiesis, stem cell maintenance, gametogenesis, melanogenesis, and in mast cell development, migration and function. This protein can be a membrane-bound or soluble protein. Mutations in this gene are associated with gastrointestinal stromal tumors, mast cell disease, acute myelogenous leukemia, and piebaldism. Multiple transcript variants encoding different isoforms have been found for this gene."[11]

Gene ID: 29126 is CD274 CD274 molecule on 9p24.1: "This gene encodes an immune inhibitory receptor ligand that is expressed by hematopoietic and non-hematopoietic cells, such as T cells and B cells and various types of tumor cells. The encoded protein is a type I transmembrane protein that has immunoglobulin V-like and C-like domains. Interaction of this ligand with its receptor inhibits T-cell activation and cytokine production. During infection or inflammation of normal tissue, this interaction is important for preventing autoimmunity by maintaining homeostasis of the immune response. In tumor microenvironments, this interaction provides an immune escape for tumor cells through cytotoxic T-cell inactivation. Expression of this gene in tumor cells is considered to be prognostic in many types of human malignancies, including colon cancer and renal cell carcinoma. Alternative splicing results in multiple transcript variants."[12]

Hypotheses

  1. Downstream core promoters may work as transcription factors even as their complements or inverses.
  2. In addition to the DNA binding sequences listed above, the transcription factors that can open up and attach through the local epigenome need to be known and specified.
  3. The function of A1BG is the same as other immunoglobulin genes possessing the immunoglobulin domain cl11960 and/or any of three immunoglobulin-like domains: pfam13895, cd05751 and smart00410 in the order and nucleotide sequence: cd05751 Location: 401 → 493, smart00410 Location: 218 → 280, pfam13895 Location: 210 → 301 and cl11960 Location: 28 → 110.
