一般描述

Mastoparan-7 is an analog of the mastoparan peptide. It is present in the venom of Vespula lewisii. It was originally isolated from wasp venom.

应用

Mastoparan-7 has been used to study mastoparan-stimulated nucleotide binding to G proteins.

生化/生理作用

Mastoparan-7 (Mas-7) stimulates the G protein subunit Gαo/i by its mode of action (to bind to the plasma membrane). It possesses antiviral activity and is associated with histamine release from mast cells. It is also involved in the induction of potent mitochondrial permeability and tumor cell cytotoxicity.

分析说明

More potent analog of mastoparan.

Three BODIPY GTPgammaS analogs (FL, 515, and TR), BODIPY FL GppNHp and BODIPY FL GTP molecules were synthesized as possible fluorescent probes to study guanine nucleotide binding spectroscopically. Binding to G(alphao) increases baseline analog fluorescence by 6-, 8.5-, 2.8-, 3.5-

G protein-coupled receptors (GPCRs) transduce their signals through trimeric G proteins, inducing guanine nucleotide exchange on their Galpha-subunits; the resulting Galpha-GTP transmits the signal further inside the cell. GoLoco domains present in many proteins play important roles in multiple trimeric

Mastoparan-7 (Mas-7), an analogue of the peptide mastoparan, which is derived from wasp venom, is a direct activator of Pertussis toxin- (PTX-) sensitive G proteins. Mas-7 produces several biological effects in different cell types; however, little is known about how

The wasp venom, mastoparan (MP), activates reconstituted pertussis toxin (PTX)-sensitive G-proteins in a receptor-independent manner. We studied the effects of MP and its analogue, mastoparan 7 (MP 7), on G-protein activation in HL-60 cells and a reconstituted system and on

Mastoparan, a tetradecapeptide found in wasp venom that stimulates G-proteins, increases insulin secretion from beta-cells. In this study, we have examined the role of heterotrimeric G-proteins in mastoparan-induced insulin secretion from the insulin-secreting beta-cell line beta-TC3.
