چکیده

A non-ionic detergent such as Lubrol-PX extracts in soluble form the VIP-binding structures of rat liver plasma membranes. Detergent-solubilized proteins bind specifically [125I]VIP and the complex tracer-protein is identified by the use of Sepharose 6B columns. The interaction is only possible in the absence of detergent (below 0.001%) and is inhibited by native peptide. A molecular weight of about 80,000 was estimated for VIP-binding proteins by reference to a series of globular markers of proteins. Binding to VIP soluble proteins is specific and dependent on time as studied by the Hummel and Dreyer (Biochim. Biophys. Acta 63:530-532, 1962) assay.

The rat liver vasoactive intestinal peptide binding site. Molecular characterization by covalent cross-linking and evidence for differences from the intestinal receptor.

To identify the molecular components of the vasoactive intestinal peptide (VIP) binding sites in the liver, 125I-labelled VIP was covalently linked to liver membranes by using the cleavable cross-linker dithiobis(succinimidylpropionate). Purified rat liver plasma membranes were incubated with 125I-VIP, washed and treated with 1 mM-cross-linker. Polyacrylamide-gel electrophoresis of membrane pro...

Effect of an Antagonist of Vasoactive Intestinal Polypeptide on Biological Rhythm of Rest Activity in the Rat

Abstract Vasoactive Intestinal Polypeptide (VIP), has been found in different neurotransmitter systems and exists in various nerve tracts in the brain. Potential role of this peptide in physiological processes such as regulation of sleep and wakefulness, and biological rhythms has been confirmed in several reports. In the present research effects of intracerebroventricular (ICV) injection of a...

Nucleotide regulation of vasoactive intestinal peptide binding to bovine thyroid plasma membranes.

The specific binding of vasoactive intestinal peptide (VIP) to bovine thyroid plasma membranes is inhibited by guanine nucleotides. Guanosine 5'-triphosphate (GTP) and the non-hydrolyzable GTP analogs guanosine 5'-beta,gamma-imidotriphosphate (Gpp(NH)p) and guanosine 5'-O-(3-thiotriphosphate) (GTP-gamma-S) inhibited markedly the binding of VIP to its receptors. This inhibition was higher with G...

Characteristics of receptors for VIP in rat peritoneal macrophage membranes.

Vasoactive intestinal peptide (VIP) receptors were investigated in rat peritoneal macrophage membranes (RPMM) using [125I]VIP as ligand. The receptor binding was rapid, reversible, saturable, specific, and dependent on time, temperature, and membrane concentration. The Scatchard analysis of binding data was consistent with the existence of two classes of VIP binding sites with Kd values of 0.60...

Pharmacology, molecular identification and functional characteristics of vasoactive intestinal peptide receptors in human breast cancer cells.

High-performance liquid chromatography-purified 125I-vasoactive intestinal peptide (VIP) bound to T-47D human breast cancer cells in a specific, saturable, and reversible manner. Scatchard plots were compatible with the presence of one class of VIP receptors with high affinity (Kd = 4.5 X 10(-10) M VIP, and Bmax = 293 fmol/mg protein). The neuropeptide and its natural analogues inhibited the bi...
