The human C2orf43 protein, also known as chromosome 2 open reading frame 43, is a poorly characterized protein encoded by the C2orf43 gene located on 2p13.3. It is evolutionarily conserved across mammals but lacks extensive functional annotation. Structurally, it is predicted to contain intrinsically disordered regions (IDRs) at the N-terminus and an α-helical domain at the C-terminus, suggesting potential roles in protein-protein interactions or conformational adaptability.
Experimental studies localize C2orf43 to both the cytoplasm and nucleus, though its precise subcellular functions remain unclear. Limited evidence links it to cellular stress responses, DNA damage repair, and apoptosis regulation. In disease contexts, C2orf43 has been marginally associated with cancer progression, with altered expression observed in colorectal, ovarian, and hepatocellular carcinomas. For instance, elevated C2orf43 levels in tumors correlate with poor prognosis, implying a potential oncogenic role.
Notably, C2orf43 interacts physically with HSP90 and PCNA, key players in protein folding and DNA replication, respectively. These interactions hint at possible involvement in chaperone-mediated processes or genome stability maintenance. Post-translational modifications, including phosphorylation sites, further suggest regulatory complexity. Despite these clues, mechanistic insights remain sparse. Current research focuses on elucidating its role in tumorigenesis, chemoresistance pathways, and crosstalk with cellular signaling networks. Its functional ambiguity positions C2orf43 as an emerging target for exploratory studies in cell biology and cancer therapeutics.
