Summary of MAPK8
The gene codes for a protein, mitogen-activated protein kinase 8. The kinase plays a role in UV radiation induced apoptosis. Studies of a mouse counterpart suggest that it plays an important function in T cell proliferation, apoptosis and differentiation. [R].
The Function of MAPK8
JNK1 isoforms display different binding patterns: beta-1 preferentially binds to c-Jun, whereas alpha-1, alpha-2, and beta-2 have a similar low level of binding to both c-Jun or ATF2. However, there is no correlation between binding and phosphorylation, which is achieved at about the same efficiency by all isoforms.

Enzyme Regulation:
Activated by threonine and tyrosine phosphorylation by either of two dual specificity kinases, MAP2K4 and MAP2K7. MAP2K4 shows a strong preference for Tyr-185 while MAP2K7 phosphorylates Tyr-183 preferentially. Inhibited by dual specificity phosphatases, such as DUSP1. Inhibited by SERPINB3.
