Function
May play a role in cell differentiation, proliferation and apoptosis. 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 acts as a key regulator of disk morphogenesis. Involved in regulation of MAPK and Akt signaling pathways. In neuroblastoma cells suppresses cell differentiation such as neurite outgrowth in a RET-dependent manner.

Mechanism Description CD133 activates the PI3K/AKT, AKT/Wnt and other signaling pathways and affects the behavior of CD133+ cells, thereby playing a major role in cancer therapy. In addition, CD133 is also involved in the regulation of tumor resistance. Long-term chemotherapy leads to a significant increase in CD133 expression. Targeting CD133 can reverse drug resistance in colorectal cancer via the AKT/NF-kappa-B/multidrug resistance protein (MDR)1 pathway.

Mechanism Description The miR-142-3p was markedly decreased in coloncancer specimens, in which it was negatively correlated withthe expression of CD133, Lgr5, and ABCG2. Transfection of miR-142-3p mimics in colon cancer cells downregulated cyclin D1expression, induced G1phase cell cycle arrest, and elevatedthe sensitivity of the cells to 5-fluorouracil. Furthermore,OCT4 suppressed miR-142-3p, and hypomethylation of theOCT4promoter was associated with a reduction in miR-142-3p.
