ERK3, Human (L290V, His)

ERK3 Protein, an atypical MAPK, phosphorylates MAP2 and MAPKAPK5. Interacting with MAPKAPK5, ERK3/MAPK6 undergoes Ser-189 phosphorylation, facilitating MAPKAPK5 activation. Activated MAPKAPK5 reciprocally phosphorylates ERK3/MAPK6. The complex's precise functional implications, especially in cell cycle entry, remain elusive. ERK3 Protein, Human (L290V, His) is the recombinant human-derived ERK3 protein, expressed by E. coli , with N-6*His labeled tag.
