Abbreviation for radioimmunoprecipitation.
RIPK1A gene on chromosome 6p25.2 that encodes a serine/threonine/tyrosine kinase which transduces inflammatory and cell-death signals (necroptosis), triggered in response to the binding of ligands to death receptors, activation of pathogen recognition receptors (PRRs) and DNA damage. Activation of TNFR1 by TNF-alpha family cytokines recruits TRADD and TRAF2 to the receptor; ubiquitination by TRAF2 enhances communication with downstream signal transducers in the mitogen-activated protein kinase (MAPK) and NF-kappaB pathways, activating genes that encode inflammatory molecules. Polyubiquitinated protein binds to IKBKG/NEMO, the regulatory subunit of the IKK complex, a critical event for NF-kappaB activation. Interaction with other cellular RHIM-containing adapters initiates gene activation and cell death. RIPK1 and RIPK3 form a necroptosis-inducing complex.
