GeneCards Summary for RIPK1 Gene
RIPK1 (Receptor (TNFRSF)-Interacting Serine-Threonine Kinase 1) is a Protein Coding gene. Among its related pathways are Immune System and Signaling by GPCR. GO annotations related to this gene include identical protein binding and protein kinase activity. An important paralog of this gene is RIPK3.
UniProtKB/Swiss-Prot for RIPK1 Gene
Serine-threonine kinase which transduces inflammatory and cell-death signals (programmed necrosis) following death receptors ligation, activation of pathogen recognition receptors (PRRs), and DNA damage. Upon activation of TNFR1 by the TNF-alpha family cytokines, TRADD and TRAF2 are recruited to the receptor. Phosphorylates DAB2IP at Ser-728 in a TNF-alpha-dependent manner, and thereby activates the MAP3K5-JNK apoptotic cascade. Ubiquitination by TRAF2 via Lys-63-link chains acts as a critical enhancer of communication with downstream signal transducers in the mitogen-activated protein kinase pathway and the NF-kappa-B pathway, which in turn mediate downstream events including the activation of genes encoding inflammatory molecules. Polyubiquitinated protein binds to IKBKG/NEMO, the regulatory subunit of the IKK complex, a critical event for NF-kappa-B activation. Interaction with other cellular RHIM-containing adapters initiates gene activation and cell death. RIPK1 and RIPK3 association, in particular, forms a necrosis-inducing complex.
