title: Oleate-induced translocation of protein kinase C to hepatic microsomal membranes.
abstract: The incubation of rat liver homogenates in the presence of oleate induces the translocation of protein kinase C from the cytosol to the endoplasmic reticulum membranes. The half-maximal effect was obtained at 0.3 mM oleate. The redistribution of this enzyme induced by oleate was also obtained with purified protein kinase C and hepatic microsomal membranes. This effect seems to be mediated by long-chain fatty acids since translocation was not obtained with esterified derivatives.
