Chromosome 11 open reading frame one, also known as C11orf1, is a protein-coding gene.[1] It has been found by yeast two hybrid screen to bind to SETDB1 a histone protein methyltranferase enzyme. SETDB1 has been implicated in Huntington's disease, a neurodegenerative disorder.[2]
C11orf1 is a nuclear protein with unknown function but has been shown to show preferential expression in some disease states in microarray data.[3][4]
C11orf1 shows conservation through mammals and orthologs can be found in sea squirts and sea anemone. The below table shows some orthologs found using BLAST.[5]

AP001781.5-201
Protein
Structure
This protein is part of the UPF0686 superfamily. This family is characterized by the presence of a domain of unknown function (DUF)1143 shared by the family.[6] This family DUF1143 has a domain that includes almost all,149, of the 150 amino acids in the human ortholog. C11orf1 has six spicesomal variants and one unspliced variant.
Two O-(N-acetylaminogalactosyl)-L-threonine Glycosylations at position 138 and 142 on the protein sequence[9]
Two O-phospho-L-serine Phosphorylation sites at 112 and 141.[9]
Four O-phospho-L-threonine Phosphorylation sites at 59, 99, 113, and 138.[9]
Four O4'-phospho-L-tyrosine Phosphorylation sites at 64, 101, 105 and 143.[9]
Tissue distribution
C11orf1 appears to be ubiquitously expressed at low levels but particularly high expression in the parathyroid. Expression data indicate expression in most tissues.[10] This gene has also been found in one experiment to be under expressed in Huntington's disease patients while SETDB1 is over-expressed.[3]
