Gene

edit

C3orf80 is on chromosome 3 from 160,225,422 to 160,228,213 bp.[6] It spans 2,792 bases on the plus strand and contains only one exon.[5]

Neighboring genes of C3orf80 include IFT80, BRD7P2, and SMC4.[5]

Gene Orientation Location Function
IFT80 Minus strand 160,256,986-160,399,880 Part of IFT complex B[7]
BRD7P2 Plus strand 160,100,691-160,102,912 Pseudogene of BRD7[8]
SMC4 Plus strand 160,399,274-160,434,954 Part of the condensin complex[9]

Transcript

edit

The mRNA transcript of human C3orf80 contains no introns, has only one isoform, and the complete sequence has been found.[5][10]

Expression

Annotated AlphaFold model of C3orf80[12]

Expression of C3orf80 is highest in the cerebral cortex, esophagus, and colon.[13] A higher expression of C3orf80 has been observed from multiple sclerosis brain lesions.[14][15] Expression of C3orf80 has also been found by machine learning to be associated with different forms of cancer. A two-fold increase in expression was found in low-grade glioma based on whether the cells expressed CMTM3 or not.[16] A 107.61 fold increase in expression was seen after inhibition of CLIC1 in esophageal squamous cell carcinoma.[17] C3orf80 was one of three genes' expression levels found to form the best machine learning model for predicting invasive carcinoma.[18] Finally, C3orf80 was one of 34 genes used in a machine learning model to predict if patients had a response to FOLFIRI chemotherapy.[19]

Protein

edit

C3orf80 is 247 amino acids long, has a molecular weight of 25.6 kDa before modifications, and has been proven to exist at the protein level, however, the tertiary structure is unknown.[6] The protein is annotated to be a single-pass membrane protein, localizing at the cell membrane.[20] The amino acid sequence of C3orf80 contains a signal peptide, transmembrane region, disordered region, glycosylation, and domain of unknown function 4719 (DUF4719).[20]

Within humans, there is 0.02 ppm of C3orf80, a relatively low amount compared to other proteins.[21] Immunochemical staining has shown protein localization in cilia of glandular cells of the human fallopian tube.[22]

Evolution

Orthologs

edit

Orthologs of human C3orf80 are specific to vertebrates.[23] The farthest ortholog of human C3orf80 is found in Callorhinchus milii, with a date of divergence of 462 million years ago.[24] Orthologs can be found in all major groups from Chondrichthyes to Mammalia; however, Aves have very unique orthologs of C3orf80 compared to any other group.[25][26]
