The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
This peptide may be used for neutralization and control experiments with the polyclonal antibody that reacts with this product and human G protein alpha inhibitor 1/2, catalog ab3522. Using a solution of peptide of equal volume and concentration to the corresponding antibody will yield a large molar excess of peptide (~ 70-fold) for competitive inhibition of antibody-protein binding reactions.

Adenylate cyclase-inhibiting G alpha protein

Guanine nucleotide-binding protein G(i) subunit alpha-1
FunctionGuanine nucleotide-binding proteins (G proteins) are involved as modulators or transducers in various transmembrane signaling systems. The G(i) proteins are involved in hormonal regulation of adenylate cyclase: they inhibit the cyclase in response to beta-adrenergic stimuli. The inactive GDP-bound form prevents the association of RGS14 with centrosomes and is required for the translocation of RGS14 from the cytoplasm to the plasma membrane. May play a role in cell division.
Sequence similaritiesBelongs to the G-alpha family. G(i/o/t/z) subfamily.
Cellular localizationNucleus. Cytoplasm. Cell membrane. Cytoplasm > cytoskeleton > centrosome. Localized at the plasma membrane throughout mitosis. Colocalizes with RIC8A and RGS14 at the plasma membrane (By similarity). Localizes in the centrosomes of interphase and mitotic cells, but not in centrosomes during cytokinesis. Detected at the cleavage furrow or the midbody.
