Enhanced degradation of EGF receptors by a sorting nexin, SNX1
R C Kurten et al. Science. 1996.
Abstract
The vectorial movement of proteins requires specific recognition by components of the vesicular trafficking machinery. A protein, sorting nexin-1 (SNX1), was identified in a human cell line that bound to a region of the epidermal growth factor receptor (EGFR) containing the lysosomal targeting code. SNX1 contains a region of homology to a yeast vacuolar sorting protein, and overexpression of SNX1 decreased the amount of EGFR on the cell surface as a result of enhanced rates of constitutive and ligand-induced degradation. Thus, SNX1 is likely to play a role in sorting EGFR to lysosomes.
