The human protein encoded by the C20orf135 gene (Chromosome 20 Open Reading Frame 135), also termed 20q13.12-derived protein, remains poorly characterized, reflecting its relatively recent identification through genomic sequencing efforts. Located on chromosome 20, this gene is evolutionarily conserved across mammals, suggesting functional importance, though its specific biological roles are not yet fully elucidated. Current annotations classify it as a putative intracellular protein, potentially involved in basic cellular processes. Structural predictions indicate a conserved α-helical-rich domain, with possible post-translational modification sites, hinting at regulatory interactions. Limited experimental studies link its expression to certain tissues, including the brain, testes, and kidneys, though expression levels appear moderate. Interestingly, bioinformatics analyses associate C20orf135 with cellular stress responses, and sparse evidence suggests potential involvement in modulating cell proliferation or apoptosis pathways. Its upregulation in select cancer types (e.g., gliomas, prostate cancer) has been sporadically reported, though mechanistic insights remain lacking. Recombinant forms of the protein have been produced in vitro using bacterial or mammalian expression systems to enable antibody generation and functional assays, yet no disease-specific therapeutic applications have been validated. Ongoing research aims to clarify its interactome, signaling networks, and relevance to human pathologies, positioning C20orf135 as a candidate for exploratory studies in cell biology and disease biomarker discovery.
