TBK1 (TANK-binding kinase 1) is an enzyme with kinase activity. Specifically, it is a serine / threonine protein kinase.[5] It is encoded by the TBK1 gene in humans.[6] This kinase is mainly known for its role in innate immunity antiviral response. However, TBK1 also regulates cell proliferation, apoptosis, autophagy, and anti-tumor immunity.[5] Insufficient regulation of TBK1 activity leads to autoimmune, neurodegenerative diseases or tumorigenesis.[7][8]
