CC -!- FUNCTION: Serine/threonine-protein kinase that acts downstream of ERK
CC (MAPK1/ERK2 and MAPK3/ERK1) signaling and mediates mitogenic and
CC stress-induced activation of transcription factors, regulates
CC translation, and mediates cellular proliferation, survival, and
CC differentiation. May function as tumor suppressor in epithelial ovarian
CC cancer cells (By similarity). {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + L-seryl-[protein] = ADP + H(+) + O-phospho-L-seryl-
CC [protein]; Xref=Rhea:RHEA:17989, Rhea:RHEA-COMP:9863, Rhea:RHEA-
CC COMP:11604, ChEBI:CHEBI:15378, ChEBI:CHEBI:29999, ChEBI:CHEBI:30616,
CC ChEBI:CHEBI:83421, ChEBI:CHEBI:456216; EC=2.7.11.1;
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + L-threonyl-[protein] = ADP + H(+) + O-phospho-L-
CC threonyl-[protein]; Xref=Rhea:RHEA:46608, Rhea:RHEA-COMP:11060,
CC Rhea:RHEA-COMP:11605, ChEBI:CHEBI:15378, ChEBI:CHEBI:30013,
CC ChEBI:CHEBI:30616, ChEBI:CHEBI:61977, ChEBI:CHEBI:456216;
CC EC=2.7.11.1;
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000250};
CC -!- ACTIVITY REGULATION: Upon extracellular signal or mitogen stimulation,
CC phosphorylated at Thr-570 in the C-terminal kinase domain (CTKD) by
CC MAPK1/ERK2 and MAPK3/ERK1. The activated CTKD then autophosphorylates
CC Ser-377, allowing binding of PDPK1, which in turn phosphorylates Ser-
CC 218 in the N-terminal kinase domain (NTDK) leading to the full
CC activation of the protein and subsequent phosphorylation of the
CC substrates by the NTKD.
CC -!- SUBUNIT: Forms a complex with either MAPK1/ERK2 or MAPK3/ERK1 in
CC quiescent cells. Transiently dissociates following mitogenic
CC stimulation (By similarity). Interacts with FBXO5; cooperate to induce
CC the metaphase arrest of early blastomeres; increases and stabilizes
CC interaction of FBXO5 with CDC20 (PubMed:15526037). {ECO:0000250,
CC ECO:0000269|PubMed:15526037}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250}. Cytoplasm {ECO:0000250}.
CC -!- PTM: Activated by phosphorylation at Ser-218 by PDPK1.
CC Autophosphorylated on Ser-377, as part of the activation process. May
CC be phosphorylated at Thr-356 and Ser-360 by MAPK1/ERK2 and MAPK3/ERK1
CC (By similarity). {ECO:0000250}.
CC -!- PTM: N-terminal myristoylation results in an activated kinase in the
CC absence of added growth factors. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the protein kinase superfamily. AGC Ser/Thr
CC protein kinase family. S6 kinase subfamily. {ECO:0000305}.
