Serine/threonine/tyrosine kinase that plays an essential role in modulation of innate and adaptive immune responses. Upon stimulation by bacterial peptidoglycans, NOD1 and NOD2 are activated, oligomerize and recruit RIPK2 through CARD-CARD domains. Contributes to the tyrosine phosphorylation of the guanine exchange factor ARHGEF2 through Src tyrosine kinase leading to NF-kappaB activation by NOD2. Once recruited, RIPK2 autophosphorylates and undergoes 'Lys-63'-linked polyubiquitination by E3 ubiquitin ligases XIAP, BIRC2 and BIRC3. The polyubiquitinated protein mediates the recruitment of MAP3K7/TAK1 to IKBKG/NEMO and induces 'Lys-63'-linked polyubiquitination of IKBKG/NEMO and subsequent activation of IKBKB/IKKB. 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. Plays also a role during engagement of the T-cell receptor (TCR) in promoting BCL10 phosphorylation and subsequent NF-kappa-B activation. Plays a role in the inactivation of RHOA in response to NGFR signaling.


Autophosphorylated. Autophosphorylation at Tyr-474 is necessary for effective NOD2 signaling. Phosphorylated. Phosphorylation at Tyr-381 by Src kinase CSK occurs in a ARHGEF2-dependent manner and is required for NOD2-dependent innate immune activation.

Ubiquitinated on Lys-209; undergoes 'Lys-63'-linked polyubiquitination catalyzed by ITCH. Polyubiquitinated with 'Lys-48' and 'Lys-63'-linked chains by BIRC2/c-IAP1 and BIRC3/c-IAP2, leading to activation of NF-kappa-B. Also undergoes 'Met-1'-linked polyubiquitination; the head-to-tail linear polyubiquitination is mediated by the LUBAC complex in response to NOD2 stimulation. Linear polyubiquitination is restricted by FAM105B/otulin, probably to limit NOD2-dependent proinflammatory signaling activation of NF-kappa-B.

Detected in heart, brain, placenta, lung, peripheral blood leukocytes, spleen, kidney, testis, prostate, pancreas and lymph node.


Found in a signaling complex consisting of at least ARHGEF2, NOD2 and RIPK2. Interacts with ARHGEF2; the interaction mediates tyrosine phosphorylation of RIPK2 by Src kinase CSK. Binds to CFLAR/CLARP and CASP1 via their CARD domains. Binds to BIRC3/c-IAP1 and BIRC2/c-IAP2, TRAF1, TRAF2, TRAF5 and TRAF6. May be a component of both the TNFRSF1A and TNRFSF5/CD40 receptor complex. Interacts with NOD1. Interacts (via CARD domain) with NOD2 (via CARD domain). Interacts with MAP3K4; this interaction sequesters RIPK2 from the NOD2 signaling pathway. Interacts with IKBKG/NEMO. The polyubiquitinated protein interacts with MAP3K7/TAK1. Interacts with XIAP/BIRC4. Interacts with NLRP10. Interacts with CARD9. Interacts with INAVA; the interaction takes place upon PRR stimulation. Interacts (via CARD domain) with NGFR (via death domain).


Contains an N-terminal kinase domain and a C-terminal caspase activation and recruitment domain (CARD) that mediates the recruitment of CARD-containing proteins.

Belongs to the protein kinase superfamily. TKL Ser/Thr protein kinase family.
