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