Product Overview
This rabbit polyclonal antibody detects TGF-beta-activated kinase 1 and MAP3K7-binding protein 3 (gene TAB3) in human samples and is validated for Western blot, flow cytometry and ELISA. The predicted molecular weight is 78.7 kDa, and the supplier reports an observed band at about 90 kDa.
TAB3 is a close paralog of TAB2 that binds Lys63-linked polyubiquitin chains through its NZF zinc finger and connects TAK1 to TRAF6-containing complexes. By promoting TAK1 activation it feeds into NF-κB and JNK signaling, and it is studied in innate immunity and inflammatory signaling.
