Informações sobre genes

human ... PROM1(8842)

Descrição geral

Prominin-1 (UniProt: O43490; also known as Antigen AC133, Prominin-like protein 1, CD133) is encoded by the PROM1 (also known as PROML1, MSTP061) gene (Gene ID: 8842) in human. CD133 (Prominin-1) is multi-pass cell-surface glycoprotein that plays a role in cell differentiation, proliferation and apoptosis. It binds cholesterol in cholesterol-containing plasma membrane microdomains and may play a role in the organization of the apical plasma membrane in epithelial cells. During early retinal development CD133 acts as a key regulator of disk morphogenesis. Defects in PROM1 gene are known to cause retinitis pigmentosa, cone-rod dystrophy, and retinal macular dystrophy 2. Higher levels of CD133 have been reported in several cancer cell types, including various leukemias, retinoblastomas, glioblastomas, and kidney carcinomas. Higher levels of CD133 are also observed in pancreatic, gastric, colorectal, and hepatocellular cancers. It is also considered as a marker of stem cells in the adult small intestine that are susceptible to transformation into tumors retaining a fraction of mutant Prom1+ tumor cells. (Ref.: Zhu, L., et al. (2009). Nature 477 (7229); 603-607).
