The internalization of yeast Ste6p follows an ordered series of events involving phosphorylation, ubiquitination, recognition and endocytosis.

Abstract excerpt

A general pathway for the internalization of plasma membrane proteins that involves phosphorylation, ubiquitination, recognition and endocytosis has recently emerged from multiple studies in yeast. We refer to this series of events as the PURE pathway. Here we investigate whether the yeast a-factor transporter Ste6p, an ATP-binding cassette protein, utilizes the PURE pathway. Deletion of a 52-amino acid sequence...
