Description:
Tyrosine-based signals within the cytoplasmic domain of integral membrane proteins mediate clathrin-dependent protein sorting in the endocytic and secretory pathways. A yeast two-hybrid system was used to identify proteins that bind to tyrosine-based signals. The medium chains (mu 1 and mu 2) of two clathrin-associated protein complexes (AP-1 and AP-2, respectively) specifically interacted with tyrosine-based signals of several integral membrane proteins. The interaction was confirmed by in vitro binding assays. Thus, it is likely that the medium chains serve as signal-binding components of the clathrin-dependent sorting machinery.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ohno, H -- Stewart, J -- Fournier, M C -- Bosshart, H -- Rhee, I -- Miyatake, S -- Saito, T -- Gallusser, A -- Kirchhausen, T -- Bonifacino, J S -- New York, N.Y. -- Science. 1995 Sep 29;269(5232):1872-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cell Biology and Metabolism Branch, National Institute of Child Health and Human Development, National Institutes of Health, Bethesda, MD 20892, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7569928" target="_blank"〉PubMed〈/a〉
