Interrogation of ...The huntingtin (HTT) protein plays critical roles in numerous cellular pathways by functioning as a scaffold for its many interaction partners and HTT knock out is embryonic lethal. Interrogation of HTT function is complicated by the large size of this protein so we studied a suite of structure-rationalized subdomains to investigate the structure-function relationships within the HTT-HAP40 complex. Protein samples derived from the subdomain constructs were validated using biophysical methods and cryo-electron microscopy, revealing they are natively folded and can complex with validated binding partner, HAP40. Derivatized versions of these constructs enable protein-protein interaction assays in vitro, with biotin tags, and in cells, with luciferase two-hybrid assay-based tags, which we use in proof-of-principle analyses to further interrogate the HTT-HAP40 interaction. These open-source biochemical tools enable studies of fundamental HTT biochemistry and biology, will aid the discovery of macromolecular or small-molecule binding partners and help map interaction sites across this large protein. #1: ![]() タイトル: Expanding the Huntingtons disease research toolbox; validated huntingtin subdomain constructs for biochemical and structural investigation of the huntingtin protein 著者: Alteen, M.G. / Deme, J.C. / Alvarez, C.P. / Loppnau, P. / Hutchinson, A. / Seitova, A. / Chandrasekaran, R. / Silva Ramos, E. / Secker, E. / Alqazzaz, M. / Wanker, E.E. / Lea, S.M. / ...著者: Alteen, M.G. / Deme, J.C. / Alvarez, C.P. / Loppnau, P. / Hutchinson, A. / Seitova, A. / Chandrasekaran, R. / Silva Ramos, E. / Secker, E. / Alqazzaz, M. / Wanker, E.E. / Lea, S.M. / Arrowsmith, C.H. / Harding, R.J. | ||||||
