CC -!- FUNCTION: May play a role in the response to environmental stress and
CC cytokines. Appears to regulate translation by phosphorylating EIF4E,
CC thus increasing the affinity of this protein for the 7-methylguanosine-
CC containing mRNA cap. {ECO:0000269|PubMed:9155017}.
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 Evidence={ECO:0000269|PubMed:9155017};
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 EC=2.7.11.1; Evidence={ECO:0000269|PubMed:9155017};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000269|PubMed:9155017};
CC -!- ACTIVITY REGULATION: Phosphorylated and activated by the p38 kinases
CC and kinases in the Erk pathway. {ECO:0000269|PubMed:9155017}.
CC -!- SUBUNIT: Interacts with the C-terminal regions of EIF4G1 and EIF4G2.
CC Also binds to dephosphorylated ERK1 and ERK2, and to the p38 kinases.
CC {ECO:0000269|PubMed:9155017}.
CC -!- TISSUE SPECIFICITY: Ubiquitously expressed in all tissues examined,
CC with high levels in skeletal muscle. {ECO:0000269|PubMed:9155017}.
CC -!- PTM: Dual phosphorylation of Thr-209 and Thr-214 activates the kinase.
CC Phosphorylation of Thr-344 activates the kinase. MAPK3/ERK1 is one of
CC the kinases which activate MKNK1/MNK1. Phosphorylation by PAK2 leads to
CC a reduced phosphorylation of EIF4G1 (By similarity). {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the protein kinase superfamily. CAMK Ser/Thr
CC protein kinase family. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAH21369.1; Type=Erroneous initiation; Evidence={ECO:0000305};
