Mitogen-activated protein kinase kinase kinase 7-interacting protein 2 ; TAK1-binding protein 2 ; TAB-2 ; TGF-beta-activated kinase 1-binding protein 2 ; KIAA0733 ; MAP3K7IP2
Categories
Elisa
Function
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.
Specificity
Natural and recombinant Human TGF-beta-activated kinase 1 and MAP3K7-binding protein 2
Subcellular Location
Membrane Peripheral membrane protein Cytoplasm cytosol Following IL1 stimulation, translocation occurs from the membrane to cytosol.
Interacts with MAP3K7 and TRAF6. Identified in the TRIKA2 complex composed of MAP3K7, TAB1 and TAB2. Binds 'Lys-63'-linked polyubiquitin chains. Interacts with NCOR1 and HDAC3 to form a ternary complex. Interacts (via C-terminal) with NUMBL (via PTB domain). Interacts (via the C-terminus) with WDR34 (via WD domains). Interacts with RBCK1.
