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.
Specificity
Natural and recombinant Bovine Regulator of G-protein signaling 19
Subcellular Location
Membrane Lipid-anchor
Entryname
RGS19_BOVIN
Linearity
The linearity of the kit was assayed by testing samples spiked with appropriate concentration of RGS19 and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.
Intra-assay Precision (Precision within an assay):Three samples of known concentration were tested twenty times on one plate to assess intra-assay precision.
Intra-Assay CV: ≤4.2%
Inter-assay Precision (Precision between assays):Three samples of known concentration were tested in five separate assays to assess inter-assay precision.
Inter-Assay CV: ≤8.4%
Protein Name
Regulator of G-protein signaling 19
Recovery
Recovery was determined by spiking various levels of RGS19 into serum and plasma .
