1 We demonstrated previously that growth hormone (GH) induces tyrosyl phosphorylation of SIRPalpha and association of SIRPalpha with SHP-2. cyclo(tyrosyl-tyrosyl) growth hormone 1 Homo sapiens
2 We demonstrated previously that growth hormone (GH) induces tyrosyl phosphorylation of SIRPalpha and association of SIRPalpha with SHP-2. cyclo(tyrosyl-tyrosyl) growth hormone 1 Homo sapiens
3 The GH-activated tyrosine kinase JAK2 associates with and tyrosyl-phosphorylates SIRPalpha1. cyclo(tyrosyl-tyrosyl) growth hormone 1 Homo sapiens
4 GH-dependent tyrosyl phosphorylation of JAK2 is reduced when wild-type SIRPalpha1 compared with SIRPalpha1 lacking the four cytoplasmic tyrosines (SIRP 4YF) is expressed in cells, suggesting that SIRPalpha1 negatively regulates GHR/JAK2 signaling. cyclo(tyrosyl-tyrosyl) growth hormone 1 Homo sapiens
