Human DAPK1: death-associated protein kinase 1, active enzyme, calmodulin dependent serine-threonine kinase
The Death-associated protein kinase (DAPK) is a Ca2+/calmodulin (CaM) regulated Ser/Thr kinase, which is ubiquitously expressed but frequently reduced in various human tumor cell lines and tissues. Activation occurs in response to death stimuli (TNF-α, C6-ceramide and INF-γ) upon an increased Ca2+ level and dephosphorylation of an inhibitory site. DAPK1 acts as tumor supressor and mediates apoptotic events e.g. by upregulation of p53 and subsequently induction of the caspase-dependent cell death. On the other hand, depending on cell system and specific death signal, induction of DAPKs can lead to autophagic cell death with effects on the cytoskeleton.
