The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 1 µg/ml. Predicted molecular weight: 77 kDa. Optimal concentration of antibody depends the protein level in a given sample. Our recommended concentrations are the starting point for general use. Customers are advised have to do a series of titration tests to determine optimal concentration. Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.
機能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(t)-alpha. Involved in phototransduction; key element in the recovery phase of visual transduction.
組織特異性Highly expressed in the caudate and putamen, lower levels found in the hypothalamus and nucleus accumbens and very low levels in cerebellum. Not expressed in globus pallidus or cingulate cortex. Isoform 2 is expressed predominantly in pineal gland and retina. Isoform 3 is expressed in retina (abundant in photoreceptors).
関連疾患Defects in RGS9 are a cause of prolonged electroretinal response suppression (PERRS) [MIM:608415]; also known as bradyopsia. PERRS is characterized by difficulty adjusting to sudden changes in luminance levels mediated by cones.
配列類似性Contains 1 DEP domain. Contains 1 G protein gamma domain. Contains 1 RGS domain.
ドメインIn photoreceptor cells the DEP domain is essential for targeting RGS9 to the outer rod segments.
翻訳後修飾Retinal isoform 3 is light-dependent phosphorylated at 'Ser-478'. Phosphorylation is decreased by light exposition.
細胞内局在Membrane. Isoform 3 is targeted to the membrane via its interaction with RGS9BP.
