Although many microvillar cytoskeletal components have been identified, the molecular basis of microvillus formation is largely undefined. Here, we report that the Wiskott-Aldrich syndrome protein (WASp) is necessary for rhabdomere microvillus morphogenesis. We show that WASp accumulates on the photoreceptor apical surface before microvillus formation, and at the time of microvillus initiation WASp colocalizes with amphiphysin and moesin. The loss of WASp delays the enrichment of F-actin on the apical photoreceptor surface, delays the appearance of the primordial microvillar projections, and subsequently leads to malformed rhabdomeres.<\/jats:p>","DOI":"10.1083\/jcb.200307048","type":"journal-article","created":{"date-parts":[[2004,1,27]],"date-time":"2004-01-27T01:33:41Z","timestamp":1075167221000},"page":"417-426","update-policy":"https:\/\/doi.org\/10.1083\/jcb.crossmarkpolicy","source":"Crossref","is-referenced-by-count":35,"title":["WASp is required for the correct temporal morphogenesis of rhabdomere microvilli"],"prefix":"10.1083","volume":"164","author":[{"given":"Andrew C.","family":"Zelhof","sequence":"first","affiliation":[{"name":"Division of Biology, University of California, San Diego, La Jolla, CA 92093"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robert W.","family":"Hardy","sequence":"additional","affiliation":[{"name":"Division of Biology, University of California, San Diego, La Jolla, CA 92093"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"291","published-online":{"date-parts":[[2004,1,26]]},"reference":[{"key":"2023072214525172600_BIB1","doi-asserted-by":"crossref","first-page":"1993","DOI":"10.1083\/jcb.110.6.1993","volume":"110","year":"1990","journal-title":"J.
