>cd06625 STKc_MEKK3_like Serine/threonine kinases (STKs), MAP/ERK kinase kinase 3 (MEKK3)-like subfamily, catalytic (c) domain. STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. The MEKK3-like subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase. This subfamily is composed of MEKK3, MEKK2, and related proteins, all containing an N-terminal PB1 domain, which mediates oligomerization, and a C-terminal catalytic domain. MEKK2 and MEKK3 are mitogen-activated protein kinase (MAPK) kinase kinases (MAPKKKs or MKKKs or MAP3Ks), proteins that phosphorylate and activate MAPK kinases (MAPKKs or MKKs or MAP2Ks), which in turn phosphorylate and activate MAPKs during signaling cascades that are important in mediating cellular responses to extracellular signals.
