CD133 / PROM1 / Prominin 1 Protein (Fc tag) (recombinant rat)

Protein Construction: A DNA sequence encoding the rat PROM1 (NP_001103607.1) (Asn171-Tyr424) was with the Fc region of mouse IgG1 at the N-terminus. Sequence: Asn171-Tyr424. Fusion tag: N-Fc Endotoxin: < 1.0 EU per µg of the protein as determined by the LAL method Apparent Molecular Mass: 67 and 34 kDa. Protein function: CD133, also known as PROM1 and Prominin 1, is a pentaspan transmembrane glycoprotein which belongs to the prominin family. It localizes to membrane protrusions and is often expressed on adult stem cells. CD133 is known to play a role in maintaining stem cell properties by suppressing differentiation. CD133 binds cholesterol in cholesterol-containing plasma membrane microdomains. It is proposed to play a role in apical plasma membrane organization of epithelial cells. CD133 is also involved in regulation of MAPK and Akt signaling pathways. Mutations in PROM1 gene have been shown to result in retinitis pigmentosa and Stargardt disease. PROM1 gene is expressed from at least five alternative promoters that are expressed in a tissue-dependent manner. Expression of this gene is also associated with several types of cancer.
