Detailed entry information

Protein Information (annotations from UniProt)

Database IDHIV0001782
UniProt IDQ9BUB5
Primary gene name(s)MKNK1
Synonym gene name(s)MNK1
Protein nameMAP kinase-interacting serine/threonine-protein kinase 1
Protein functionMay play a role in the response to environmental stress and cytokines. Appears to regulate translation by phosphorylating EIF4E, thus increasing the affinity of this protein for the 7-methylguanosine-containing mRNA cap. {ECO:0000269|PubMed:11463832, ECO:0000269|PubMed:15350534, ECO:0000269|PubMed:9155018, ECO:0000269|PubMed:9878069}.
