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	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.	Tyrosine	72-80	mitogen-activated protein kinase kinase 3	Homo sapiens	122-126
