PKRD1 Antibody – Rabbit Polyclonal

PRKD1 is a serine/threonine kinase that regulates a variety of cellular functions, including membrane receptor signaling, transport at the Golgi, protection from oxidative stress at the mitochondria, gene transcription, and regulation of cell shape, motility, and adhesion (summary by Eiseler et al., 2009 [PubMed 19329994]).[supplied by OMIM, Nov 2010]

PRKD1: a CAMK kinase of the PKD family. Cleavage by caspase-3 following DNA damage activates it and alters its subcellular localization. Sensitizes cells to apoptosis induced by genotoxic stress. Its cleavage is blocked in cells that over-express the anti-apoptotic Bcl-x(L) protein. Expression of a caspase-resistant mutant partially inhibits DNA damage-induced apoptosis. Its activation by TLR ligands is dependent on MyD88, IRAK4 and -1, but not TRAF6. Essential for MyD88-dependent proinflammatory immune responses. Activated by diacylglycerol and phorbol esters. Binds to the trans-Golgi network and regulates the fission of transport carriers specifically destined to the cell surface. Colocalizes with F-actin at peripheral F-actin-rich structures in membrane ruffles at the edge of lamellipodia in cervical carcinoma cells. Substrates reportedly include critical regulatory proteins including CREB, SSH1L, CTNNB1, HDACs 5 and 7, PKD1, HPK1, MARK2, PIP5K2A, PPP1R14A
