WebDec 30, 1998 · Stat3βtc was quantitatively phosphorylated by this kinase domain. Gel filtration chromatography revealed a Stat3βtc dimer. Y705 was identified as the major … Among a number of various molecules, Receptor Tyrosine Kinases (RTKs) play a critical role in transducing signals through a range of signaling pathways. All RTKs consists of an extracellular ligand binding region, a single transmembrane helix and a cytoplasmic region (the tyrosine kinase domain). Prior to ligand stimulation most RTKs present as a monomer on the surface of cells. Ligand binding to the extracellular domain induces dimerization. Dimerization of RTKs leads to a… trump\u0027s incoherent ramblings

WebTyrosine Phosphotyrosine When a growth factor binds to the extracellular domain of a RTK, its dimerization is triggered with other adjacent RTKs. Dimerization leads to a rapid activation of the protein's cytoplasmic kinase domains, the first substrate for these domains being the receptor itself. WebDec 30, 1998 · Stat3βtc was quantitatively phosphorylated by this kinase domain. Gel filtration chromatography revealed a Stat3βtc dimer. Y705 was identified as the major phosphorylated residue of Stat3βtc. This corresponds to the tyrosine residue which is phosphorylated by the Janus kinase in vivo. WebOne receptor in the dimer/oligomer then phosphorylates one or more tyrosines in a neighboring RTK, and the phosphorylated receptor then serves as a site for assembly (and activation) of intracellular signaling proteins ( Ullrich and Schlessinger, 1990 ).
