摘要
Two related transmembrane proteins in mammalian cells bind the mannose 6-phosphate recognition marker present on all soluble lysosomal hydrolases. Recent studies of cells that express only one or neither of these proteins have shed light Mot only on their function in directing lysosomal enzymes into the endocytic pathway but also on their critical role in transport vesicle formation in the trans Golgi network. One of these proteins also binds insulin-like growth factor II (IGF-II) and may be an important part of the IGF-dependent system that regulates development.
