It binds two moles of GTP, one at an exchangeable site on the beta chain and one at a non-exchangeable site on the alpha chain (By similarity).[RuleBase:RU003505][SAAS:SAAS023123_004_019801] Publication Abstract from PubMed Tau is a protein involved in the regulation of axonal microtubules in neurons. In pathological conditions, it forms filamentous aggregates which are molecular markers of neurodegenerative diseases known as tauopathies. Structures of Tau in fibrils or bound to the microtubule have been reported. We present here a structure of a Tau construct comprising the PHF6 motif, an oligopeptide involved in Tau aggregation, as a complex with tubulin. This Tau fragment binds as a dimer to a new site which, when transposed to the microtubule, would correspond to a pore between protofilaments. These results raise new hypotheses on Tau-induced microtubule assembly and stabilization and on Tau oligomerization. The structure of a Tau fragment bound to tubulin prompts new hypotheses on Tau mechanism and oligomerization.,Ammar Khodja L, Campanacci V, Lippens G, Gigant B PNAS Nexus. 2024 Oct 30;3(11):pgae487. doi: 10.1093/pnasnexus/pgae487. , eCollection 2024 Nov.
