Dapk2, Death-associated protein kinase 2
Enzyme Classification 22.214.171.124
Also Known as
Calcium/calmodulin-dependent serine/threonine kinase involved in multiple cellular signaling pathways that trigger cell survival, apoptosis, and autophagy. Capable of regulating both type I apoptotic and type II autophagic cell death signals. The former involves caspase activation, chromatin and mitochondrial condensation while the latter involves caspase-independent cell death in conjunction with accumulation of mature autophagic vesicles, plasma membrane blebs, and nuclear condensation without DNA degradation. Mediator of anoikis and a suppressor of beta-catenin-dependent anchorage-independent growth of malignant epithelial cells. May play a role in granulocytic maturation (By similarity). Regulates granulocytes motility by controlling cell spreading and polarization (PubMed:24163421). Homodimer in its autoinhibited state. Active as monomer. Interacts with 14-3-3 proteins YWHAB, YWHAE, YWHAG, YWHAH, YWHAQ, YWHAZ and SFN; the interaction requires DAPK2 phosphorylation at Thr-369 and suppresses DAPK2 kinase activity and DAPK2-induced apoptosis.
