General Description
DAP-kinase 1 is a Ca
2+/calmodulin dependent Ser/Thr kinase that associates with microfilaments. The protein is composed of a multidomain structure. It has a subdomain typical of serine/threonine kinases, a Ca
2+/calmodulin regulatory domain, eight ankyrin repeats followed by two P-loop motifs and a typical death domain module. It contains two auto-inhibitory domains, one being Ca
2+/calmodulin dependent.
Biochem/physiol Actions
Death-associated protein kinase (DAPK) belongs to the serine/threonine kinase family that regulates apoptosis, growth factor signaling and also may be involved in modulating immune responses. DAPK1 mediates cellular functions such as membrane blebbing and autophagy and inhibits the activity of prolyl isomerase
