This gene encodes a member of the receptor-interacting protein (RIP) family of serine/threonine protein kinases. The encoded protein contains a C-terminal caspase activation and recruitment domain (CARD), and is a component of signaling complexes in both the innate and adaptive immune pathways. It is a potent activator of NF-kappaB and inducer of apoptosis in response to various stimuli.,RIPK2,CARD3,CARDIAK,CCK,GIG30,RICK,RIP2,Cancer,Invasion and Metastasis,Signal Transduction,Kinase,Serine/threonine kinases,MAPK-JNK Signaling Pathway,MAPK-P38 Signaling Pathway,Cell Biology & Developmental Biology,Apoptosis,Caspases,Death receptors & ligands,Inhibition of Apoptosis,Death Receptor Signaling Pathway,Endocrine & Metabolism,Endocrine and metabolic diseases,Obesity,Immunology & Inflammation,NF-kB Signaling Pathway,Toll-like Receptor Signaling Pathway,Cell Intrinsic Innate Immunity Signaling Pathway,TLR Signaling,RIPK2
