Serine/threonine/tyrosine-protein kinase that plays an essential role in modulation of innate and adaptive immune responses (PubMed : 14638696, PubMed : 17054981, PubMed : 21123652, PubMed : 28656966, PubMed : 9575181, PubMed : 9642260). Acts as a key effector of NOD1 and NOD2 signaling pathways : upon activation by bacterial peptidoglycans, NOD1 and NOD2 oligomerize and recruit RIPK2 via CARD-CARD domains, leading to the formation of RIPK2 filaments (PubMed : 17054981, PubMed : 17562858, PubMed : 21123652, PubMed : 22607974, PubMed : 28656966, PubMed : 29452636, PubMed : 30026309). Once recruited, RIPK2 autophosphorylates and undergoes 'Lys-63'-linked polyubiquitination by E3 ubiquitin ligases XIAP, BIRC2 and BIRC3, as well as 'Met-1'-linked (linear) polyubiquitination by the LUBAC complex, becoming a scaffolding protein for downstream effectors (PubMed : 22607974, PubMed : 28545134, PubMed : 29452636, PubMed : 30026309, PubMed : 30279485, PubMed : 30478312). 'Met-1'-linked polyubiquitin chains attached to RIPK2 recruit IKBKG/NEMO, which undergoes 'Lys-63'-linked polyubiquitination in a RIPK2-dependent process (PubMed : 17562858, PubMed : 22607974, PubMed : 29452636, PubMed : 30026309). 'Lys-63'-linked polyubiquitin chains attached to RIPK2 serve as docking sites for TAB2 and TAB3 and mediate the recruitment of MAP3K7/TAK1 to IKBKG/NEMO, inducing subsequent activation of IKBKB/IKKB (PubMed : 18079694). In turn, NF-kappa-B is released from NF-kappa-B inhibitors and translocates into the nucleus where it activates the transcription of hundreds of genes involved in immune response, growth control, or protection against apoptosis (PubMed : 18079694). The protein kinase activity is dispensable for the NOD1 and NOD2 signaling pathways (PubMed : 29452636, PubMed : 30026309). Contributes to the tyrosine phosphorylation of the guanine exchange factor ARHGEF2 through Src tyrosine kinase leading to NF-kappa-B activation by NOD2 (PubMed : 21887730). Also involved in adaptive immunity : plays a role during engagement of the T-cell receptor (TCR) in promoting BCL10 phosphorylation and subsequent NF-kappa-B activation (PubMed : 14638696). Plays a role in the inactivation of RHOA in response to NGFR signaling (PubMed : 26646181).
