(Lymphoma, T-Cell) :
Purified p56lck both tyrosyl phosphorylated and stimulated the seryl-threonyl phosphotransferase activity of purified p44mpk , a MAP kinase isoform from sea star oocytes
Childs et al., Biochem Cell Biol 1993
:
Although it has been demonstrated that p44mpk can be activated in vitro through phosphorylation by the tyrosine kinase p56lck , neither of the brain kinases were significantly stimulated by the tyrosine kinases p56lck, p56lyn, or p59fyn
