RIPK1

Gene
RIPK1
Protein
Receptor-interacting serine/threonine-protein kinase 1
Organism
Homo sapiens
Length
671 amino acids
Function
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 (PubMed:11101870, PubMed:17389591, PubMed:19524512, PubMed:19524513). Upon activation of TNFR1 by the TNF-alpha family cytokines, TRADD and TRAF2 are recruited to the receptor (PubMed:11101870, PubMed:17389591, PubMed:19524512, PubMed:19524513). Phosphorylates DAB2IP at 'Ser-728' in a TNF-alpha-dependent manner, and thereby activates the MAP3K5-JNK apoptotic cascade (PubMed:17389591). 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 (PubMed:15258597). 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 (PubMed:15258597). RIPK1 and RIPK3 association, in particular, forms a necrosis-inducing complex (PubMed:19524513, PubMed:19524512).
