Here we show that cycloheximide is nontoxic and its effect is reversible, allowing protein synthesis to reinitiate. Upon cycloheximide removal protein synthesis restarted and by 1 hour the amyloid precursor protein\u2014 green fluorescent protein could be clearly detected, permitting the monitoring of amyloid precursor protein anterograde transport, particularly the secretory pathway. The consensus NPTY motif in amyloid precursor protein, typically associated with endocytosis, was mutated to NPTF or NPTE to mimic a constitutively dephosphorylated or phosphorylated residue, respectively. Our data reveal that disruption of this motif affects amyloid precursor protein endocytosis, as shown previously, but also its incorporation into trans-Golgi network budding vesicles. Thus, cycloheximide can be a useful tool to study both anterograde and retrograde ``in vivo'' protein transport.<\/jats:p>","DOI":"10.1177\/1533317508323572","type":"journal-article","created":{"date-parts":[[2008,12,23]],"date-time":"2008-12-23T14:04:57Z","timestamp":1230041097000},"page":"602-608","source":"Crossref","is-referenced-by-count":12,"title":["Monitoring ``De Novo'' APP Synthesis by Taking Advantage of the Reversible Effect of Cycloheximide"],"prefix":"10.1177","volume":"23","author":[{"given":"Sandra","family":"Rebelo","sequence":"first","affiliation":[{"name":"Laborat\u00f3rio de Neuroci\u00eancias Centro de Biologia Celular, Universidade de Aveiro, Aveiro, Portugal"}]},{"given":"Sandra Isabel","family":"Vieira","sequence":"additional","affiliation":[{"name":"Laborat\u00f3rio de Neuroci\u00eancias Centro de Biologia Celular, Universidade de Aveiro, Aveiro, Portugal"}]},{"given":"Edgar F.","family":"da Cruz e Silva","sequence":"additional","affiliation":[{"name":"Laboratorio de Transdu\u00e7ao de Sinais Centro de Biologia Celular, Universidade de Aveiro, Aveiro, Portugal"}]},{"given":"Odete A.
