Abstract
Transforming growth factor-β (TGF-β) activated kinase 1 (TAK1), also named mitogen-activated protein kinase 7 (MAPK7), forms a pivotal signaling complex with TAK1-binding proteins (TAB1, TAB2, and TAB3), orchestrating critical biological processes, including immune responses, cell growth, apoptosis, and stress responses. Activation of TAK1 by stimuli, such as tumor necrosis factor α (TNFα), interleukin-1β (IL-1β), and Toll-like receptors (TLRs), underscores its central role in cellular signaling. Given the critical role of the TAK1-binding protein (TAK1-TAB) complex in cellular signaling and its impact on various biological processes, this review seeks to understand how ubiquitination thoroughly regulates the TAK1-TAB complex. This understanding is vital for developing targeted therapies for diseases where this signaling pathway is dysregulated. The exploration is significant as it unveils new insights into the activity, stability, and assembly of the complex, underscoring its therapeutic potential in disease modulation.
