In TCR-CD3/CD28-co-stimulated T-cells, is required for the activation of NF-kappa-B and JUN, which in turn are essential for IL2 production, and participates in the calcium-dependent NFATC1 and NFATC2 transactivation. Mediates the activation of the canonical NF-kappa-B pathway (NFKB1) by direct phosphorylation of CARD11 on several serine residues, inducing CARD11 association with lipid rafts and recruitment of the BCL10-MALT1 complex, which then activates IKK complex, resulting in nuclear translocation and activation of NFKB1.\n\nOpen Targets scores its association with cancer at 0.61 (direct and indirect evidence; datatypes literature 0.93, animal model 0.80, genetic association 0.17, clinical 0.92).","asOf":"2026-09-23","links":[{"label":"HGNC HGNC:9410","url":"https://www.genenames.org/data/gene-symbol-report/#!/hgnc_id/HGNC:9410"},{"label":"UniProt Q04759","url":"https://www.uniprot.org/uniprotkb/Q04759/entry"},{"label":"NCBI Gene 5588","url":"https://www.ncbi.nlm.nih.gov/gene/5588"},{"label":"Ensembl ENSG00000065675","url":"https://www.ensembl.org/Homo_sapiens/Gene/Summary?g=ENSG00000065675"}],"tags":["cancer-genes-wave"],"related":["open-targets"],"cancers":["leukaemia","myeloproliferative-neoplasms","systemic-mastocytosis","aml"],"sections":[],"technologies":[],"targets":[],"drugs":[],"companies":[],"institutions":[],"pathways":[],"terms":[],"trials":[],"people":[],"bottlenecks":[],"keyPapers":[],"journals":[],"dependsOn":[],"notes":["Written by scripts/fetch-cancer-genes.ts from CIViC, Open Targets, IntOGen, HGNC and UniProt; the function text is UniProt's, condensed and in UK spelling.

May also play an indirect role in activation of the non-canonical NF-kappa-B (NFKB2) pathway. In the signalling pathway leading to JUN activation, acts by phosphorylating the mediator STK39/SPAK and may not act through MAP kinases signalling. Plays a critical role in TCR/CD28-induced NFATC1 and NFATC2 transactivation by participating in the regulation of reduced inositol 1,4,5-trisphosphate generation and intracellular calcium mobilisation.
