Description

The expression region of this recombinant Human TAB2 covers amino acids 401-693. This TAB2 protein is theoretically predicted to have a molecular weight of 37.1 kDa. The TAB2 protein was expressed in baculovirus. The N-terminal 10xHis tag and C-terminal Myc tag was fused into the coding gene segment of TAB2, making it easier to detect and purify the TAB2 recombinant protein in the later stages of expression and purification.

TGF-beta-activated kinase 1 and MAP3K7-binding protein 2 (TAB2) is a protein of significant research interest. Its studies focus on signal transduction and immune regulation. TAB2 plays a crucial role in the TGF-beta signaling pathway, regulating cellular processes such as proliferation, differentiation, and apoptosis. In the area of immune regulation, TAB2 is involved in modulating inflammatory responses and immune cell functions. Recent studies suggest a potential association of TAB2 with the onset and progression of tumors. This positions TAB2 as a key molecule in research areas such as immunology, cancer, and signal transduction.

Target Background

Function

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). Acts as an adapter linking MAP3K7/TAK1 and TRAF6 to 'Lys-63'-linked polyubiquitin chains. 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. Regulates the IL1-mediated translocation of NCOR1 out of the nucleus. Involved in heart development.
