Invitrogen™ Human TAOK1, GST Tag Recombinant Protein

TAOK1 is a serine/threonine-protein kinase involved in regulation of the p38-containing stress-responsive MAP kinase pathway and extracellular signal-regulated protein kinase (ERK) kinases (MEKs). The activation of and binding to MEK3 by TAOK1 implicates TAOK1 in the regulation of the p38-containing stress-responsive MAP kinase pathway. A microtubule affinity-regulating kinase, TAOK1 (also known as MARKK) is an important regulator of mitotic progression, required for both chromosome congression and checkpoint-induced anaphase delay. TAOK1 is 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.
