DescriptionRIP3 is a novel member of RIP Ser/Thr kinase family. It is a potent inducer of apoptosis and is an important component of TNFR1 signaling complex. RIP3 consists of an N-terminal RIP-like-Kinase domain and a unique, non-homologous C-terminus responsible for caspase activation and apoptosis induction. RIP3 is expressed in multiple tissues including hematopoietic cells and plays a functional role in the regulation of apoptosis and NF-kB signaling. It is recruited to the TNFR1 signaling complex in a RIP-dependant manner where it induces apoptosis by activating caspases and/or inhibiting TNFR1-induced NF-kB activation. RIP3 negatively regulates the TLR3-Trif-mediated NF-kB signaling pathway by competing with the binding of Trif to RIP1. The human RIP3 gene is localized in the chromosomal region 14q11.2.
