PRAME family member 8 (PRAMEF8)

PRAME family member 8 (PRAMEF8) is a human protein in the PRAME (Preferentially Expressed Antigen in Melanoma) family, classified as a cancer/testis antigen. PRAMEF8 is predicted to act as a ubiquitin-like ligase substrate adaptor, participating in the proteasome-mediated degradation of proteins via the Cul2-RING ubiquitin ligase complex and is likely active in the cytoplasm. The PRAME protein family, including PRAMEF8, is notable for testis-restricted expression in normal tissues and broad upregulation in various cancers. While most functional and drug/interventional focus is on the prototypical PRAME, PRAMEF8 shares key domain features and is implicated in tumor cell biology, including potential roles in regulating transcription, cell proliferation, and cancer prognosis. As with the PRAME family, PRAMEF8 could serve as a biomarker and potential immunotherapeutic target, though specific therapies and drugs remain in early research stages.
