class="title"> Abstract </h2> <div class="abstract-content selected" id="eng-abstract"> <p> <strong class="sub-title"> Background: </strong> Sonic hedgehog (Shh) signal transduction involves the ligand binding Patched1 (Ptc1) protein and a signaling component, Smoothened (Smo). A select group of compounds inhibits both Shh signaling, regulated by Ptc1, and late endosomal lipid sorting, regulated by the Ptc-related Niemann-Pick C1 (NPC1) protein. This suggests that Ptc1 regulates Smo activity through a common late endosomal sorting pathway also utilized by NPC1. During signaling, Ptc accumulates in endosomal compartments, but it is unclear if Smo follows Ptc into the endocytic pathway. </p> <p> <strong class="sub-title"> Results: </strong> We characterized the dynamic subcellular distributions of Ptc1, Smo, and activated Smo mutants individually and in combination. Ptc1 and Smo colocalize extensively in the absence of ligand and are internalized together after ligand binding, but Smo becomes segregated from Ptc1/Shh complexes destined for lysosomal degradation. In contrast, activated Smo mutants do not colocalize with nor are cotransported with Ptc1. Agents that block late endosomal transport and protein sorting inhibit the ligand-induced segregation of Ptc1 and Smo. We show that, like NPC1-regulated lipid sorting, Shh signal transduction is blocked by antibodies that specifically disrupt the internal membranes of late endosomes, which provide a platform for protein and lipid sorting. </p> <p> <strong class="sub-title"> Conclusions: </strong> These data support a model in which Ptc1 inhibits Smo only when in the same compartment. Ligand-induced segregation allows Smo to signal independently of Ptc1 after becoming sorted from Ptc1/Shh complexes in the late endocytic pathway. </p> </div> </div> <p class="disclaimer" id="disclaimer"> <a href="/disclaimer/" target="_blank" ga_category="literature_resources" ga_action="disclaimer_link" ga_label="under_abstract">PubMed Disclaimer</a> </p> <div class="similar-articles" id="similar"> <h2 class="title"> Similar articles </h2> <ul class="articles-list" id="similar-articles-list"> <li class="full-docsum"> <div class="docsum-content" style="display:inline;"> <a class="docsum-title" href="/10021362/" ref="article_id=10021362&linksrc=similar_articles_link&ordinalpos=1" data-ga-category="similar_article" data-ga-action="10021362" data-ga-label=""> Sonic hedgehog signaling by the patched-smoothened receptor complex. </a> <div class="docsum-citation full-citation"> <span class="docsum-authors full-authors">Murone M, Rosenthal A, de Sauvage FJ.</span> <span class="docsum-authors short-authors">Murone M, et al.</span> <span class="docsum-journal-citation full-journal-citation">Curr Biol. 1999 Jan 28;9(2):76-84. doi: 10.1016/s0960-9822(99)80018-9.</span> <span class="docsum-journal-citation short-journal-citation">Curr Biol. 1999.</span> <span class="citation-part">PMID: <span class="docsum-pmid">10021362</span></span> </div> </div> </li> <li class="full-docsum"> <div class="docsum-content" style="display:inline;"> <a class="docsum-title" href="/19906846/" ref="article_id=19906846&linksrc=similar_articles_link&ordinalpos=2" data-ga-category="similar_article" data-ga-action="19906846" data-ga-label=""> Patched regulates Smoothened trafficking using lipoprotein-derived lipids. </a> <div class="docsum-citation full-citation"> <span class="docsum-authors full-authors">Khaliullina H, Pan谩kov谩 D, Eugster C, Riedel F, Carvalho M, Eaton S.</span> <span class="docsum-authors short-authors">Khaliullina H, et al.</span> <span class="docsum-journal-citation full-journal-citation">Development. 2009 Dec;136(24):4111-21. doi: 10.1242/dev.041392.
