Tyrosine 108-111 mitogen-activated protein kinase kinase 3 Homo sapiens 0-4 15797859-8 2005 In addition, inactivation of Src, MKK3, p38, or the EGF receptor blocked tyrosine phosphorylation of beta-catenin, a key signaling intermediate that is involved in the epithelial-mesenchymal transition and vimentin expression. Tyrosine 73-81 mitogen-activated protein kinase kinase 3 Homo sapiens 34-38 11062067-9 2000 MKK3, MKK4 and MKK6 all show a strong preference for phosphorylation of the tyrosine residue of the Thr-Gly-Tyr motifs in their known substrates SAPK2a/p38, SAPK3/p38 gamma and SAPK4/p38 delta. Tyrosine 76-84 mitogen-activated protein kinase kinase 3 Homo sapiens 0-4 21878628-4 2011 Our data show that Src kinase activity regulates IL-13-induced p38 MAPK tyrosine phosphorylation via the upstream kinases MKK3 or MKK6.
