FLT3 Protein, Human (HEK293, hFc)

FLT3 is a tyrosine-protein kinase receptor that regulates differentiation, proliferation, and survival of hematopoietic progenitor cells and dendritic cells. It phosphorylates downstream effectors such as SHC1 and AKT1, activating signaling cascades involving MTOR, RAS, and MAP kinases. FLT3 Protein, Human (HEK293, hFc) is the recombinant human-derived FLT3 protein, expressed by HEK293 , with C-hFc labeled tag.

FLT3, a tyrosine-protein kinase, functions as a cell-surface receptor for the cytokine FLT3LG, exerting regulatory control over the differentiation, proliferation, and survival of hematopoietic progenitor cells and dendritic cells. This receptor facilitates the phosphorylation of various downstream effectors, including SHC1 and AKT1, and activates signaling cascades involving MTOR, RAS, MAPK1/ERK2, and/or MAPK3/ERK1. Moreover, it plays a pivotal role in the phosphorylation of FES, FER, PTPN6/SHP, PTPN11/SHP-2, PLCG1, and STAT5A and/or STAT5B. While wild-type FLT3 activation leads to modest STAT5A or STAT5B activation, mutations causing constitutive kinase activity result in heightened cell proliferation and resistance to apoptosis, underscoring its role in fostering aberrant signaling pathways.
