Reconstitution of the L-lactate carrier from rat and rabbit erythrocyte plasma membranes.
1. Rat and rabbit erythrocyte plasma-membrane proteins were solubilized with decanoyl-N-methylglucamide and reconstituted into liposomes. The procedure includes detergent removal by gel filtration, followed by a freeze-thaw step. 2. The rate of [1-14C]pyruvate uptake into these vesicles was inhibited by approx. 70% by alpha-cyano-4-hydroxycinnamate and p-chloromercuribenzenesulphonate. The exte...
متن کاملSpecific binding of calcitonin to rat liver plasma membranes.
The binding of human calcitonin (CT) was investigated in the plasma membrane fraction obtained from normal rat liver. The liver plasma membrane bound 125I-labeled [( 125I]) human CT, with increasing concentrations of the plasma membrane protein from 4.6-80 micrograms/ml, in a both time and temperature dependent manner. Specific binding of [125I] human CT was competitively inhibited by concentra...
متن کاملVesicular transport of newly synthesized cytochromes P4501A to the outside of rat hepatocyte plasma membranes.
Anti-cytochrome P450 (CYP)1A2 autoantibodies are found in dihydralazine-induced hepatitis, and CYPs2B and 2C have been shown to follow vesicular flow to the plasma membrane (PM). However, it is unknown whether other CYPs follow this route, whether NADPH-CYP reductase is present on the hepatocyte surface, and whether autoimmune hepatitis-inducing drugs increase PM CYPs. In this study, we determi...
متن کاملIsolation of rat hepatocyte plasma membranes. I. Presence of the three major domains
A rat liver plasma membrane preparation was isolated and characterized both biochemically and morphologically. The isolation procedure was rapid, simple and effective in producing a membrane fraction with the following biochemical characteristics: approximately 40-fold enrichment in three plasma membrane markers, 5'-nucleotidase, alkaline phosphodiesterase I (both putative bile canalicular memb...
متن کاملIsolation of rat hepatocyte plasma membranes. II. Identification of membrane-associated cytoskeletal proteins
Rat liver plasma membranes were isolated as presented in the preceding paper (Hubbard, A. L., D. A. Wall, and A. Ma., 1983, J. Cell Biol., 96: 217-229) and found to contain many filaments associated both with desmosomes along the lateral surface and with the cytoplasmic aspects of membranes comprising each of the three domains (lateral [LS], bile canalicular [BC] and sinusoidal [SF] ). Exposure...
