General info

Function

Plays a key role in both adaptive and innate immune signaling by bridging CARD domain-containing proteins to immune activation (PubMed : 10187770, PubMed : 10364242, PubMed : 10400625, PubMed : 24074955, PubMed : 25365219). Acts by channeling adaptive and innate immune signaling downstream of CARD domain-containing proteins CARD9, CARD11 and CARD14 to activate NF-kappa-B and MAP kinase p38 (MAPK11, MAPK12, MAPK13 and/or MAPK14) pathways which stimulate expression of genes encoding pro-inflammatory cytokines and chemokines (PubMed : 24074955). Recruited by activated CARD domain-containing proteins : homooligomerized CARD domain-containing proteins form a nucleating helical template that recruits BCL10 via CARD-CARD interaction, thereby promoting polymerization of BCL10, subsequent recruitment of MALT1 and formation of a CBM complex (PubMed : 24074955). This leads to activation of NF-kappa-B and MAP kinase p38 (MAPK11, MAPK12, MAPK13 and/or MAPK14) pathways which stimulate expression of genes encoding pro-inflammatory cytokines and chemokines (PubMed : 18287044, PubMed : 24074955, PubMed : 27777308). Activated by CARD9 downstream of C-type lectin receptors; CARD9-mediated signals are essential for antifungal immunity (PubMed : 26488816). Activated by CARD11 downstream of T-cell receptor (TCR) and B-cell receptor (BCR) (PubMed : 18264101, PubMed : 18287044, PubMed : 24074955, PubMed : 27777308). Promotes apoptosis, pro-caspase-9 maturation and activation of NF-kappa-B via NIK and IKK (PubMed : 10187815).

Post-translational modifications

Phosphorylated. Phosphorylation results in dissociation from TRAF2 and binding to BIRC2/c-IAP2 (PubMed:11466612). Phosphorylated by IKBKB/IKKB (PubMed:17213322).. Ubiquitinated via both 'Lys-63'-linked and linear ('Met-1'-linked) polyubiquitin chains in response to T-cell receptor (TCR) activation (PubMed:18287044, PubMed:27777308). Ubiquitination is recognized by IKBKG/NEMO, the regulatory subunit of I-kappa-B kinase (IKK), and is required for TCR-induced NF-kappa-B activation (PubMed:18287044, PubMed:27777308). Linear ubiquitination at Lys-17, Lys-31 and Lys-63 is mediated by RNF31/HOIP; linear ubiquitination is recognized with much higher affinity than 'Lys-63'-linked ubiquitin by IKBKG/NEMO (PubMed:27777308). CARD11 is required for linear ubiquitination by HOIP by promoting the targeting of BCL10 to RNF31/HOIP (PubMed:27777308).. Proteolytically cleaved by MALT1; required for T-cell activation.
