receptor (TNFRSF)-interacting serine-threonine kinase 1; Involved in the transduction of TNF signaling. TNF stimulation induces binding of RIPK1-TRADD-TRAF2-TRAF5 complex to TNFR1. TRAF proteins then catalyze the 'Lys-63'-linked polyubiquitination of RIPK1, inducing RIPK1 association with the IKK complex, which is subsequently activated, leading ultimately to the activation of NF-kappa-B. The inflammatory response is kept transient by the action of the NF-kappa-B target gene product TNFAIP3. TNFAIP3 is recruited to RIPK1 within a complex comprising also RNF11, ITCH and TAX1BP1. TNFAIP3 [...] (671 aa)
