TAOK1 is a serine/threonine-protein kinase involved in various processes such as p38/MAPK14 stress-activated MAPK cascase, DNA damage response, and regulations of cytoskeleton stability. It phosphorylates MAP2K3, MAP2K6, and MARK2. TAOK1 acts as an activator of the p38/MAPK cascade by mediating phosphorylation and subsequent activation of the upsteam MAP2K3 and MAP2K6 kinases. It is involved in G-protein couples receptor signaling to p38/MAPK14. In response to DNA damage, TAOK1, is involved in the G2/M transition DNA damage checkpoint by activating the p38/MAPK14 stress-activated MAPK cascade by phosphorylaton of MAP2K3 and MAP2K6. In addition, it acts as a regulator of cytoskeleton stability and a regulator of apoptosis.
