Chromosome 1 open reading frame 162 is a protein that in humans is encoded by the C1orf162 gene. It has been found to be hypomethylated in instances of gastric cancer. ^[5]

The gene is located at p13.2 on chromosome 1 in humans and contains 8 exons.^[6] It is 11,026 bases long and is oriented on the plus strand.^[7]

Three transcript variants have been identified. Isoform 1 is the longest transcript and encodes the longest isoform. Isoform 2 uses an alternate in-frame splice site and is shorter than isoform 1. Isoform 3 lacks an alternate in-frame exon and is shorter compared to isoform 1.^[8] There are six stem loops in the 5' untranslated region and five stem loops in the 3' untranslated region.^[9]

The predicted molecular weight of the protein C1orf162 is 16.9 kdal. Its isoelectric point is approximately 9.2 in mammals.^[10] A single transmembrane region is conserved across species.^[11] The protein is predicted to localize mainly in the nucleus.^[12] The protein is predicted to be myristoylated.^[13]

C1orf162 is not ubiquitously expressed in humans. According to microarray-assessed tissue expression patterns, C1orf162 is most highly expressed in bone marrow, lung, fetal liver, lymph node, spleen, and thymus in normal human tissues.^[14] Staining of normal tissues has found high levels of RNA expression in bone marrow, lymph node, spleen, and lung tissue, which coincides with microarray-assessed expression patterns.^[15]

One study found the protein to be one of three hypomethylated proteins in instances of gastric cancer.^[16]

The gene has no known paralogs. Orthologs have been noted in many mammal species in addition to a few birds and reptiles. The transmembrane region of the protein is highly conserved across species. No orthologs have been identified in fish, insects, or prokaryotes.^[17]
