RIP3 (Receptor Interacting Protein 3, Receptor-interacting Protein 3, RIP-3, Receptor-interacting Serine/threonine Kinase 3, Receptor-interacting Serine/threonine-protein Kinase 3, RIP-like Protein Kinase 3, RIPK3)

Certain serine/threonine protein kinases, such as ASK1, RIP, DAP, and ZIP kinases, are mediators of apoptosis. Receptor interacting proteins including RIP and RIP2/RICK mediate apoptosis induced by TNFR1 and Fas, two prototype members in the death receptor family. A novel member in the RIP kinase family was recently identified and designated RIP3 (1-3). RIP3 contains N-terminal kinase domain but, unlike RIP or RIP2, lacks the C-terminal death or CARD domain. RIP3 binds to RIP and TNFR1, mediates TNFR1 induced apoptosis, and attenuates RIP and TNFR1 induced NF-kappaB activation. Overexpression of RIP3 induces apoptosis and NF-kappaB activation. The messenger RNA of RIP3 is expressed in a subset of adult tissues (2,3).\n\nApplications: \nSuitable for use in Western Blot. Other applications not tested.\n\nRecommended Dilution:\nWestern Blot: 0.5-1ug/ml\nOptimal dilutions to be determined by the researcher.\n\nPositive Control: 3T3 cell lysate\n\nStorage and Stability:\nMay be stored at 4 degrees C for short-term only. For long-term storage and to avoid repeated freezing and thawing, add sterile glycerol (40-50%), aliquot and store at -20 degrees C. Aliquots are stable for at least 3 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
