Abstract :
In response to environmental cues, certain plasma membrane proteins are ubiquitinated, signaling their endocytosis and degradation. In the budding yeast, a single enzyme, Rsp5, is charged with this task. now identify an arrestin-related family of Rsp5 adaptor proteins called ARTs that confer specificity on the ubiquitination of plasma membrane proteins and contribute to the maintenance of the correct cell surface protein repertoire.
