Protein
Mitogen-activated protein kinase 8B
Gene
mapk8b
Organism
Cyprinus carpio (Common carp)
Status
Reviewed - Annotation score: 4 out of 5 - Experimental evidence at transcript leveli

Functioni

Responds to activation by environmental stress and pro-inflammatory cytokines by phosphorylating a number of transcription factors, primarily components of AP-1 such as c-Jun and ATF2 and thus regulates AP-1 transcriptional activity By similarity.By similarity

Catalytic activityi

ATP + a protein = ADP + a phosphoprotein.

Cofactori

Magnesium By similarity.By similarity

Enzyme regulationi

Activated by threonine and tyrosine phosphorylation By similarity.By similarity
