MAPK4, Human (Sf9, His, GST)

MAPK4, an atypical MAPK protein, phosphorylates microtubule-associated protein 2 (MAP2) and MAPKAPK5, forming a complex with intricate phosphorylation events. Interaction with MAPKAPK5 leads to ERK3/MAPK6 phosphorylation at Ser-189, activating MAPKAPK5, which reciprocally phosphorylates ERK3/MAPK6. The specific cellular role of this interplay, while unclear, suggests ERK3's potential involvement in promoting entry into the cell cycle. MAPK4 Protein, Human (Sf9, His, GST) is the recombinant human-derived MAPK4 protein, expressed by Sf9 insect cells , with N-8*His, N-GST labeled tag. The total length of MAPK4 Protein, Human (Sf9, His, GST) is 586 a.a., .
