SCF Protein, Mouse
Based on 2 publication(s) in Google Scholar
SCF proteins are ligands for the KIT receptor-type protein tyrosine kinase and are critical for multiple cellular processes, including survival, proliferation, hematopoiesis, stem cell maintenance, gametogenesis, mast cell development, migration, and melanogenesis.Binding to KIT activates multiple signaling pathways involving PIK3R1, AKT1, GRB2, RAS, RAF1, MAP kinase, STAT family members and PLCG1, producing signaling molecules.SCF Protein, Mouse is the recombinant mouse-derived SCF protein, expressed by E.coli , with tag free.

The stem cell factor (SCF) protein serves as a ligand for the receptor-type protein-tyrosine kinase KIT, playing a crucial role in the regulation of various cellular processes. Its functions encompass the control of cell survival and proliferation, hematopoiesis, stem cell maintenance, gametogenesis, mast cell development, migration, and melanogenesis. Upon binding with KIT, SCF activates multiple signaling pathways, including the phosphorylation of PIK3R1 and subsequent activation of AKT1. The interaction also triggers signaling cascades involving GRB2, RAS, RAF1, and the MAP kinases MAPK1/ERK2 and/or MAPK3/ERK1. Furthermore, SCF and KIT promote the activation of STAT family members (STAT1, STAT3, and STAT5), as well as PLCG1, leading to the production of diacylglycerol and inositol 1,4,5-trisphosphate as cellular signaling molecules. Acting synergistically with other cytokines, likely interleukins, SCF forms a homodimer non-covalently linked and a heterotetramer with KIT, facilitating KIT dimerization and subsequent activation through autophosphorylation.
