Ligand for the receptor-type protein-tyrosine kinase KIT. Plays an essential role in the regulation of cell survival and proliferation,hematopoiesis,stem cell maintenance,gametogenesis,mast cell development,migration and function,and in melanogenesis. KITLG/SCF binding can activate several signaling pathways. Promotes phosphorylation of PIK3R1,the regulatory subunit of phosphatidylinositol 3-kinase,and subsequent activation of the kinase AKT1. KITLG/SCF and KIT also transmit signals via GRB2 and activation of RAS,RAF1 and the MAP kinases MAPK1/ERK2 and/or MAPK3/ERK1. KITLG/SCF and KIT promote activation of STAT family members STAT1,STAT3 and STAT5. KITLG/SCF and KIT promote activation of PLCG1,leading to the production of the cellular signaling molecules diacylglycerol and inositol 1,4,5-trisphosphate. KITLG/SCF acts synergistically with other cytokines,probably interleukins.Source:Recombinant protein corresponding to aa26-189 from human KITLG,fused to GST-Tag at N-terminal,expressed in E. coli.Molecular Weight: ~45.5kDAA Sequence:EGICRNRVTNNVKDVTKLVANLPKDYMITLKYVPGMDVLPSHCWISEMVVQLSDSLTDLLDKFSNISEGLSNYSIIDKLVNIVDDLVECVKENSSKDLKKSFKSPEPRLFTPEEFFRIFNRSIDAFKDFVVASETSDCVVSSTLSPEKDSRVSVTKPFMLPPVAStorage and Stability: May be stored at 4°C for short-term only.
