  • Target

    • Function
      Regulates G protein-coupled receptor signaling cascades. Inhibits signal transduction by increasing the GTPase activity of G protein alpha subunits, thereby driving them into their inactive GDP-bound form (PubMed:11063746, PubMed:19478087). Plays a role in the regulation of blood pressure in response to signaling via G protein-coupled receptors and GNAQ. Plays a role in regulating the constriction and relaxation of vascular smooth muscle (By similarity). Binds EIF2B5 and blocks its activity, thereby inhibiting the translation of mRNA into protein (PubMed:19736320).
    • Tissue specificity
      Expressed in acute myelogenous leukemia (AML) and in acute lymphoblastic leukemia (ALL).
    • Sequence similarities
      Contains 1 RGS domain.
    • Post-translational
      Phosphorylated by protein kinase C. Phosphorylation by PRKG1 leads to activation of RGS2 activity.
    • Cellular localization
      Cell membrane. Mitochondrion and Cell membrane. Cytoplasm. Nucleus, nucleolus.

    • Anti-RGS2 antibody (ab36561) at 1 µg/ml + Human brain tissue lysate - total protein (ab29466) at 10 µg

      IRDye 680 Conjugated Goat Anti-Rabbit IgG (H+L) at 1/10000 dilution

      Performed under reducing conditions.

      Predicted band size: 24 kDa
      Observed band size: 23 kDa
      why is the actual band size different from the predicted?
      Additional bands at: 51 kDa (possible cross reactivity)

    • ICC/IF image of ab36561 stained human SH-SY5Y cells. The cells were PFA fixed (10 min), permabilised in TBS-T (20 min) and incubated with the antibody (ab36561, 1µg/ml) for 1h at room temperature. 1%BSA / 10% normal goat serum / 0.3M glycine was used to quench autofluorescence and block non-specific protein-protein interactions. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red). DAPI was used to stain the cell nuclei (blue).

    • ab36561 staining RGS2 in human heart tissue section by Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections). Tissue underwent fixation in formaldehyde, heat mediated antigen retrieval in Citrate buffer pH 6.0 and blocking (5 minutes/peroxidase block then 10 minutes/protein block) for 15 minutes at 20°C. The primary antibody was diluted, 1/250 and incubated with sample for 45 minutes at 20°C. A HRP conjugated goat polyclonal to rabbit IgG was used undiluted as secondary.
