| Type | activity regulation | Description | Activated by DAG and phorbol esters. Phorbol-ester/DAG-type domain 1 binds DAG with high affinity and appears to play the dominant role in mediating translocation to the cell membrane and trans-Golgi network. Phorbol-ester/DAG-type domain 2 binds phorbol ester with higher affinity. Autophosphorylation of Ser-748 and phosphorylation of Ser-744 by PKC relieves auto-inhibition by the PH domain. Phosphorylation on Tyr-469 by the SRC-ABL1 pathway in response to oxidative stress, is also required for activation. Activated by DAPK1 under oxidative stress (By similarity). |
