The United States National Library of Medicine (NLM) is a biomedical library in the United States as part of the National Institutes of Health that contains "hierarchical classifications of widely distributed protein domain families [and records] conserved sites associated with molecular function, so that they can be mapped onto user queries in support of hypothesis-driven biomolecular research."[1]

"At the time of writing, the CDD version v3.17 is the live production version with 52,910 protein- and protein domain-models obtained from Pfam (1), SMART (2), the COGs collection (3), TIGRFAMS (4), the NCBI Protein Clusters collection (5), NCBIfam (6) and CDD’s in-house data curation effort (7)."[1]

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)."[2]

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."[3]

"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."[2]

"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."[2]

"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 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."[4]

Gene ID: 2204 is FCAR Fc fragment of IgA receptor on 19q13.42: "This gene is a member of the immunoglobulin gene superfamily and encodes a receptor for the Fc region of IgA. The receptor is a transmembrane glycoprotein present on the surface of myeloid lineage cells such as neutrophils, monocytes, macrophages, and eosinophils, where it mediates immunologic responses to pathogens. It interacts with IgA-opsonized targets and triggers several immunologic defense processes, including phagocytosis, antibody-dependent cell-mediated cytotoxicity, and stimulation of the release of inflammatory mediators. Multiple alternatively spliced transcript variants encoding different isoforms have been described for this gene."[5]

Gene ID: 11026 is LILRA3 leukocyte immunoglobulin like receptor A3 on 19q13.4: "This gene encodes a member of a family of immunoreceptors that are expressed predominantly in monocytes and B cells, and at lower levels in dendritic cells and natural killer cells. The encoded protein lacks the transmembrane region found in other members of this family. It acts as a soluble receptor for class I major histocompatibility complex (MHC) antigens. Alternatively spliced transcript variants encoding different isoforms have been found. This gene is located in a cluster of related genes on chromosome 19 and is polymorphic in human populations, with many individuals containing a deletion of this genomic region."[11]

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 β†’ 493, smart00410 Location: 218 β†’ 280, pfam13895 Location: 210 β†’ 301 and cl11960 Location: 28 β†’ 110.
