TGF-beta-activated kinase 1 and MAP3K7-binding protein 2 (TAB2)

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 in'Thr-187'. Involved in heart development.
