DAPK1 Antibody – Rabbit Polyclonal

Death-associated protein kinase 1 is a positive mediator of gamma-interferon induced programmed cell death. DAPK1 encodes a structurally unique 160-kD calmodulin dependent serine-threonine kinase that carries 8 ankyrin repeats and 2 putative P-loop consensus sites. It is a tumor suppressor candidate. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2013]

DAPK1: a CAMK protein kinase of the Death-associated protein kinase (DAPK) family. Mediates autophagy and is a positive mediator of ER stress-induced and gamma-interferon induced programmed cell death. Catalytic activity is increased by ER stress. Inhibited by autophosphorylation of S308. DAPK -/- cells are protected from ER stress-induced cell death, and both apoptosis and autophagy are decreased. Colocalizes with the actin filament system. It is a tumor suppressor candidate, activating p53-dependent apoptosis. Expression is reduced in some cancers, and the promoter is frequently hypermethylated in invasive cancers. Increased expression and mislocalization is seen in epilepsy, where it may regulate neuronal death. A structurally unique serine-threonine kinase that carries eight ankyrin repeats and two putative P-loop consensus sites. Two isoforms of the human protein are produced by alternative splicing.
