Insulin regulation of protein traffic in rat adipose cells.

Rat adipocytes were biotinylated with cell-impermeable reagents, sulfo-N-hydroxysuccinimide-biotin and sulfo-N-hydroxysuccinimide-S-S-biotin in the absence and presence of insulin. Biotinylated and nonbiotinylated populations of the insulin-like growth factor-II/mannose 6-phosphate receptor, the transferrin receptor, and insulin-responsive aminopeptidase… (More)
