Pathogenesis in HD seems to involve the formation of neuronal intranuclear inclusions and the abnormal regulation of transcription and signal transduction. To identify previously uncharacterized htt-interacting proteins in a simple model system, we used a yeast two-hybrid screen with a\n                    <jats:italic>Caenorhabditis elegans<\/jats:italic>\n                    activation domain library. We found a predicted SH3 domain protein (K08E3.3b) that interacts with N-terminal htt in two-hybrid tests. A human homolog of K08E3.3b is the Cdc42-interacting protein 4 (CIP4), a protein involved in Cdc42 and Wiskott\u2013Aldrich syndrome protein-dependent signal transduction. CIP4 interacted\n                    <jats:italic>in vitro<\/jats:italic>\n                    with full-length htt from lymphoblastoid cells. Neuronal CIP4 immunoreactivity increased with neuropathological severity in the neostriatum of HD patients and partially colocalized to ubiquitin-positive aggregates. Marked CIP4 overexpression also was observed in Western blot from human HD brain striatum. The overexpression of CIP4 induced the death of striatal neurons. Our data suggest that CIP4 accumulation and cellular toxicity may have a role in HD pathogenesis.\n                  <\/jats:p>","DOI":"10.1073\/pnas.0437967100","type":"journal-article","created":{"date-parts":[[2003,3,4]],"date-time":"2003-03-04T13:36:00Z","timestamp":1046784960000},"page":"2712-2717","update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":63,"title":["Cdc42-interacting protein 4 binds to huntingtin: Neuropathologic and biological evidence for a role in Huntington's disease"],"prefix":"10.1073","volume":"100","author":[{"given":"S\u00e9bastien","family":"Holbert","sequence":"first","affiliation":[{"name":"Laboratory of Genomic Biology, Institut National de la Sant\u00e9 et de la Recherche M\u00e9dicale\u2013Avenir Group and Fondation Jean Dausset\u2013Centre d'Etude du Polymorphisme Humain, 75010 Paris, France;
