TBKBP1 (TANK-Binding Kinase 1 Binding Protein 1): TBKBP1 is a scaffold protein that plays a key role in regulating innate immunity and inflammatory responses. Also known as SINTBAD, it interacts with TBK1 and IKKε kinases, contributing to antiviral defense and the production of type I interferons. TBKBP1’s involvement in modulating immune signaling pathways underscores its importance in immune function and its potential as a therapeutic target in inflammatory and autoimmune conditions.
