>cd06652 STKc_MEKK2 Serine/threonine kinases (STKs), MAP/ERK kinase kinase 2 (MEKK2) subfamily, catalytic (c) domain. STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. The MEKK2 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. MEKK2 is a mitogen-activated protein kinase (MAPK) kinase kinase (MAPKKK or MKKK or MAP3K), that phosphorylates and activates the MAPK kinase MEK5 (or MKK5), which in turn phosphorylates and activates extracellular signal-regulated kinase 5 (ERK5). The ERK5 cascade plays roles in promoting cell proliferation, differentiation, neuronal survival, and neuroprotection. MEKK2 also activates ERK1/2, c-Jun N-terminal kinase (JNK) and p38 through their respective MAPKKs MEK1/2, JNK-activating kinase 2 (JNKK2), and MKK3/6. MEKK2 plays r
