CC -!- FUNCTION: Atypical MAPK protein. Phosphorylates microtubule-associated
CC protein 2 (MAP2) and MAPKAPK5. The precise role of the complex formed
CC with MAPKAPK5 is still unclear, but the complex follows a complex set
CC of phosphorylation events: upon interaction with atypical MAPKAPK5,
CC ERK3/MAPK6 is phosphorylated at Ser-189 and then mediates
CC phosphorylation and activation of MAPKAPK5, which in turn
CC phosphorylates ERK3/MAPK6. May promote entry in the cell cycle (By
CC 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 -!- 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 -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000250};
CC -!- ACTIVITY REGULATION: Activated by phosphorylation at Ser-189.
CC {ECO:0000250}.
CC -!- SUBUNIT: Heterodimer with ERK4/MAPK4. Interacts with (via FRIEDE motif)
CC MAPKAPK5 (By similarity). Interacts with UBE3A; this interaction may be
CC indirect and mediated by HERC2, possibly via HERC2 interaction with
CC NEURL4 (By similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}. Nucleus {ECO:0000250}.
CC Note=Translocates to the cytoplasm following interaction with MAPKAPK5.
CC {ECO:0000250}.
CC -!- DOMAIN: In contrast to classical MAPKs, the TXY motif within the
CC activation loop is replaced by the SEG motif, whose phosphorylation
CC activates the MAP kinases. {ECO:0000250}.
CC -!- PTM: Phosphorylated at Ser-189 by PAK1, PAK2 and PAK3 resulting in
CC catalytic activation. Phosphorylated by MAPKAPK5 at other sites (By
CC similarity). {ECO:0000250}.
CC -!- PTM: Ubiquitination at Met-1 leads to degradation by the proteasome
CC pathway. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the protein kinase superfamily. CMGC Ser/Thr
CC protein kinase family. MAP kinase subfamily. {ECO:0000305}.
