BD Transduction Laboratories™ Purified Mouse Anti-Gαt

The GTP binding regulatory proteins (G proteins) consist of three subunits: α, β, and γ. These heterotrimeric proteins function at membranes to relay signals from cell surface receptors to intracellular effectors. The α subunit is unique for each G protein and contains the site of GTP binding and hydrolysis, as well as sites for receptor and effector interactions. The βγ subunit complex interacts directly with receptors and the α subunit. The Gα protein transducin (Gαt) contains 350 amino acids and has been extensively studied as a model for G protein function. Gαt requires GTP in order to bind to its effectors. In the process of effector-Gαt binding, GTP is hydrolyzed and the βγ subunits are displaced. The free Gαt-GDP then reassociates with the βγ subunits and re-loads GTP to repeat the cycle.

This antibody is routinely tested by western blot analysis. Other applications were tested at BD Biosciences Pharmingen during antibody development only or reported in the literature.
