DESCRIPTION

Also known as TAB2_MOUSE, Tab2, Kiaa0733, Map3k7ip2. Adapter required to activate the JNK and NF-kappa-B signaling pathways through the specific recognition of 'Lys-63'-linked polyubiquitin chains by its RanBP2-type zinc finger (NZF) (By similarity). Acts as an adapter linking MAP3K7/TAK1 and TRAF6 to 'Lys-63'-linked polyubiquitin chains (By similarity). The RanBP2-type zinc finger (NZF) specifically recognizes Lys-63'-linked polyubiquitin chains unanchored or anchored to the substrate proteins such as RIPK1/RIP1: this acts as a scaffold to organize a large signaling complex to promote autophosphorylation of MAP3K7/TAK1, and subsequent activation of I-kappa-B-kinase (IKK) core complex by MAP3K7/TAK1 (PubMed:19927120). Regulates the IL1-mediated translocation of NCOR1 out of the nucleus (PubMed:12150997). Involved in heart development (By similarity). Interacts with MAP3K7 and TRAF6. Identified in the TRIKA2 complex composed of MAP3K7, TAB1 and TAB2. Binds 'Lys-63'-linked polyubiquitin chains (By similarity). Interacts with NCOR1 and HDAC3 to form a ternary complex (PubMed:12150997). Interacts (via C-terminal) with NUMBL (via PTB domain). Interacts (via the C-terminus) with DYNC2I2 (via WD domains). Interacts with RBCK1. Interacts with TRIM5 (By similarity).
