CD133, AC133, PROM1 (Prominin-1) or PROML1 (Prominin-like protein 1) is a member of the prominin family of pentaspan transmembrane glycoproteins.  CD133 is expressed from at least 5 alternative promoters in a tissue-dependent manner. CD133 may play a role in cell differentiation, proliferation and apoptosis. CD133 localizes to membrane protrusions and is expressed on adult stem cells, where it is thought to function in maintaining stem cell properties by suppressing differentiation.  CD133 is often used as a marker for hematopoietic stem and progenitor cells (HSPC) for somatic stem cell isolation.  CD133 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. CD133 is involved in regulation of MAPK and Akt signaling pathways. In neuroblastoma cells CD133 suppresses cell differentiation such as neurite outgrowth in a RET-dependent manner.  Mutations in the CD133 gene have been shown to result in retinitis pigmentosa and Stargardt disease. Expression of CD133 is also associated with several types of cancer.
