Receptor interacting serine/threonine kinase 2 (RIPK2) or RICK is a serine/threonine kinase. It contains a kinase domain at the amino-terminal, an intermediate domain and a caspase activation and recruitment domain (CARD) at the carboxy-terminal. The gene encoding RIPK2 is localized on human chromosome 8q21.3.
Biochem/physiol Actions
Receptor interacting serine/threonine kinase 2 (RIPK2) or RICK is activated during innate immune responses and acts as a scaffold for downstream effectors. It functions in nuclear factor-κB (NFκB) activation pathways. The protein also has roles in toll-like receptor (TLR)-signaling pathways and in the production of inflammatory cytokines.
