生物活性

Mas7 (Mastoparan 7), a structural analogue of mastoparan, is an activator of heterotrimeric Gi proteins and its downstream effectors.

體外研究
(In Vitro)

Mas7 (Mastoparan 7) produces several biological effects in different cell types. The effect of Mas7 on endogenous mono-ADP-ribosyltransferase activity is in the micromolar range with a maximal activation of 205% over the basal. In pertussis treated plasma membranes, it is found that the effect of Mas7 on endogenous mono-ADP-ribosyltransferase is partially blocked, which suggests the involvement of G-proteins, such as Gi or G0[1].
Mas7 is a basic tetradecapeptide isolated from isp venom, which activates guanine nucleotide-binding regulatory proteins (G-proteins) and stimulates apoptosis. In smooth muscle cells, Mas7 leads to an increase in the perfusion pressure. Vascular contraction is induced by Mas7. The vasoconstriction triggered by mas-7 exhibited a slower increase compared to that simulated by phenylephrine or vasopressin[2].
Exposure of hippocampal neurons to a low dose of Mas-7 increases dendritic spine density and spine head width in a time-dependent manner. Additionally, Mas-7 enhances postsynaptic density protein-95 (PSD-95) clustering in neurites and activates Gαo signaling, increasing the intracellular Ca2+ concentration[3].

Cell Assay
[1]

Hippocampal neurons cultured in round 35?mm coverslips at a density of 160,000 cells/coverslip are transfected with EGFP at 11 DIV. Then, at 14 DIV the neurons are placed in the imaging chamber in an isotonic solution. The EGFP-positive neurons are imaged with microscope every 5?min for 45?min after the treatment with 1?μM Mas-7. The images are processed and analyzed using ImageJ software[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
