Immunogen A synthetic peptide from human Regulator of G-protein signaling 19 (RGS19) conjugated to an immunogenic carrier protein has been used as the antigen.
Specificity Specific for RGS19.
Purification Whole serum
Alternative Name RGS19 (RGS19 Antibody Abstract)
Background G proteins mediate a number of cellular processes. The protein encoded by this gene belongs to the RGS (regulators of G-protein signaling) family and specifically interacts with G protein, GAI3. This protein is a guanosine triphosphatase-activating protein that functions to down-regulate Galpha i/Galpha q-linked signaling. Alternatively spliced transcript variants encoding the same protein isoform have been found for this gene.
Function: Inhibits signal transduction by increasing the GTPase activity of G protein alpha subunits thereby driving them into their inactive GDP-bound form. Binds to G-alpha subfamily 1 members, with the order G(i)a3 > G(i)a1 > G(o)a >> G(z)a/G(i)a2. Activity on G(z)-alpha is inhibited by phosphorylation and palmitoylation of the G-protein.
Subcellular location: Membrane, Lipid-anchor.
Tissue specificity: Highest expression in lung. Placenta, liver and heart also express high levels of GAIP. Also known as: RGS19, G-alpha-interacting protein, GAIP, GNAI3IP, RGSGAIP.
Research Area Cancer, Autophagy, Signaling, Immunology
Application Notes Use at a dilution of 1:300 to 1: 2000.
The optimal dilution should be determined by the end user.
Restrictions For Research Use only
Format Lyophilized
Reconstitution Reconstitute in 100 µL of sterile water. Centrifuge to remove any insoluble material.
Handling Advice Avoid freeze and thaw cycles.
Storage 4 °C/-20 °C
Storage Comment Maintain the lyophilised/reconstituted antibodies frozen at -20°C for long term storage and refrigerated at 2-8°C for a shorter term. When reconstituting, glycerol (1:1) may be added for an additional stability. Avoid freeze and thaw cycles.
