Receptor-interacting protein (RIP) kinases are a group of threonine/serine protein kinases with a relatively conserved kinase domain but distinct non-kinase regions. There are seven members of the RIPK family, RIPK1-7, some of which have emerged as critical effectors of immunity to infection with a diverse array of bacterial, viral, and protozoal pathogens.

RIP kinases are cellular signaling molecules that are critical for homeostatic signaling in both communicable and non-communicable disease processes. RIPK1, RIPK2, RIPK3 and RIPK7 have emerged as key mediators of intracellular signal transduction including inflammation, autophagy and programmed cell death, and are thus essential for the early control of many diverse pathogenic organisms.
