For10 points, name these proteins that phosphorylate a phenolic hydroxyl in the side chain of a certain amino acid.
Upon TÂ­cell activation, the ZAP70/Syk family of these proteins are activated, leading to the localization of the transmembrane protein "Linker for Activation of TÂ­cells," or LAT. SH2 domains allow binding to activated proteins of this kind. When activated, proteins of this kind can bind to Src or phospholipase C. JAKs are a family of intracellular proteins of this kind. Drugs that inhibit these proteins have a (*) Â­tinib suffix, and include crizotinib and erlotinib. The epidermal growth factor receptor and the insulin receptor are examples of cellÂ­surface receptors that are this kind of protein. MembraneÂ­bound enzymes of this kind dimerize upon activation. Those cellÂ­surface proteins of this type are often contrasted with GÂ­protein coupled receptors.
