C1orf159 is a protein that in human is encoded by the C1orf159 gene located on chromosome 1.[5][6] This gene is also found to be an unfavorable prognosis marker for renal and liver cancer, and a favorable prognosis marker for urothelial cancer.[7]
Gene[edit]
The Homo sapiens C1orf159 gene (UniProt ID: Q96HA4) is a gene located on the short arm of chromosome 1 at locus 1p36.33.[6] The gene is 34,247 base pairs in length, located at Chromosome 1 position 1,081,818 to 1,116,089 on the reverse strand.[8]
Transcript[edit]
The longest variant of human C1orf159 gene encodes an mRNA that is 2,432 nucleotides in length with 12 exons.[9] A promoter region was predicted using UCSC Genome Browser,[10] which is 762 nucleotides long, including a 434 nucleotide upstream of the transcriptional start site, exon 1, and a 298 nucleotide region of intron 1.[citation needed]
Protein[edit]
Isoforms[edit]
Alternative splicing of the gene creates 5 protein isoforms.[5] The longest isoform is 380 amino acids in length with a molecular mass of 40.382 kDa.[5]
| Isoform | UniProt[11] ID | Length (aa) |
|---|---|---|
| 1 | Q96HA4-1 | 380 |
| 2 | Q96HA4-2 | 185 |
| 3 | Q96HA4-3 | 189 |
| 4 | Q96HA4-4 | 198 |
| 5 | Q96HA4-5 | 254 |
Composition[edit]
C1orf159 protein is a proline- and arginine-rich, and a lysine- and glutamic acid- poor protein. The isoelectric point of the human C1orf159 protein is 10.07,[12] which is more basic than the average human proteomic protein pI of 7.36.[13]
Domain[edit]
The human C1orf159 protein contains a domain of unknown function DUF4501.[5] Although the exact function of the domain is not clear, it is thought to be a single pass-membrane protein with highly conserved cysteine residues.[citation needed]
The protein also contains a transmembrane domain at positions 144-169[11] and a signal peptide at positions 1-18.[9][11]
Structure[edit]
Alphafold predicts the structure of human C1orf159 protein to be mainly composed of alpha-helices.[14]
Post-translational modification[edit]
The predicted post-translational modifications of the C1orf159 protein includes N-linked glycosylation on asparagine at positions 104, 111, and 128.[5][15]
Homology/evolution[edit]
Orthologs[edit]
Orthologs of human C1orf159 are found in vertebrates including mammals, birds, reptiles, amphibians, and fish[16] with the most distantly related group of organisms being cartilaginous fish, with a date of divergence of approximately 450 million years ago.[17] Orthologs are not found in jawless fish or invertebrates.[16]

Evolutionary History[edit]
When compared with the evolution rate with cytochrome c and fibrinogen alpha, the C1orf159 protein has a similar evolutionary rate of change to the fast-evolving fibrinogen alpha protein, C1orf159 protein has a relatively fast evolution rate.[citation needed]
Clinical Significance[edit]
The Human Protein Atlas shows that C1orf159 is an unfavorable prognosis marker for renal and liver cancer, and a favorable prognosis marker for urothelial cancer, indicating that a high expression of C1orf159 is associated with a lower survival probability for patients with renal and liver cancer, and is associated with a higher survival probability for patients with urothelial cancer.[7]
