FunctionTTBK1_HUMAN Serine/threonine kinase which is able to phosphorylate TAU on serine, threonine and tyrosine residues. Induces aggregation of TAU.[1] Publication Abstract from PubMedTau-tubulin kinase 1 (TTBK1) is a dual-specificity (serine/threonine and tyrosine) kinase belonging to the casein kinase 1 superfamily. TTBK1 is a neuron-specific kinase that regulates tau phosphorylation. Hyperphosphorylation of tau is implicated in the pathogenesis of Alzheimer's disease. Two kinase-domain constructs of TTBK1 were expressed in a baculovirus-infected insect-cell system and purified. The purified TTBK1 kinase-domain proteins were crystallized using the hanging-drop vapor-diffusion method. X-ray diffraction data were collected and the structure of TTBK1 was determined by molecular replacement both as an apo structure and in complex with a kinase inhibitor. The structure of human tau-tubulin kinase 1 both in the apo form and in complex with an inhibitor.,Kiefer SE, Chang CJ, Kimura SR, Gao M, Xie D, Zhang Y, Zhang G, Gill MB, Mastalerz H, Thompson LA, Cacace AM, Sheriff S Acta Crystallogr F Struct Biol Commun. 2014 Feb 1;70(Pt 2):173-81. doi:, 10.1107/S2053230X14000144.
