  • Relevance
    GTP-binding proteins (G-proteins)are a family of heterotrimeric proteins that play a critical role in signal transduction by coupling cell surface, 7-transmembrane domain receptors to intracellular signaling pathways including second messenger generation (such as cyclic AMP, calcium and diacylglycerol), protein phosphorylation, ion channel activation, gene induction, cell growth and differentiation. Receptor activation catalyzes the exchange of GTP for GDP bound to the inactive G protein alpha subunit resulting in a conformational change and dissociation of the complex. The G protein alpha and beta-gamma subunits are capable of regulating various cellular effectors. Activation is terminated by a GTPase intrinsic to the G-alpha subunit.

Thank you for your inquiry and patience. ab58651 and ab58916 are different peptides against GNAS complex. Human Gnas1 and Gnas2 have 100% and 98% homology, respective to antibodies. The homology is very low against other subunits but the cross-reac...
