Cellular component

A protein complex whose core components are the receptor-interacting serine/threonine-protein kinases RIPK1 and RIPK3 (also called RIP1 and RIP3). Formation of the ripoptosome can induce an extrinsic apoptotic signaling pathway or a necroptotic signaling pathway. The composition of this protein complex may depend on several factors including nature of the signal, cell type and more.

necrosome

It has been shown that receptor-mediated necroptotic signaling pathway requires assembly of a ripoptosome protein complex consisting of caspase-8, caspase-10, Fas-associated death domain protein (FADD), casp8 and FADD-like apoptosis regulator (CFLAR) as well as the two receptor-interacting serine/threonine-protein kinases RIPK1 and RIPK3 (PMID:21737330). Optionally, depending on the receptor activated, this complex may contain TLR3 adaptor protein TRIF (PMID:21737330).
