The protein encoded by this gene is an activator of MAP3K7/TAK1, which is required for for the IL-1 induced activation of nuclear factor kappaB and MAPK8/JNK. This protein forms a kinase complex with TRAF6, MAP3K7 and TAB1, and it thus serves as an adaptor that links MAP3K7 and TRAF6. This protein, along with TAB1 and MAP3K7, also participates in the signal transduction induced by TNFSF11/RANKl through the activation of the receptor activator of NF-kappaB (TNFRSF11A/RANK), which may regulate the development and function of osteoclasts. Studies of the related mouse protein indicate that it functions to protect against liver damage caused by chemical stressors. Mutations in this gene cause congenital heart defects, multiple types, 2 (CHTD2). Alternative splicing results in multiple transcript variants. [provided by RefSeq, May 2014]
GeneCards Summary for TAB2 Gene
TAB2 (TGF-Beta Activated Kinase 1/MAP3K7 Binding Protein 2) is a Protein Coding gene.

Among its related pathways are Activated TLR4 signalling and Nucleotide-binding domain, leucine rich repeat containing receptor (NLR) signaling pathways. GO annotations related to this gene include K63-linked polyubiquitin binding. An important paralog of this gene is TAB3.
UniProtKB/Swiss-Prot for TAB2 Gene
Adapter linking MAP3K7/TAK1 and TRAF6. Promotes MAP3K7 activation in the IL1 signaling pathway. The binding of Lys-63-linked polyubiquitin chains to TAB2 promotes autophosphorylation of MAP3K7 at Thr-187. Involved in heart development.
