  • 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.

    Thank you for contacting us.
    Because we carry over 90,000 products, it isn't feasible for us to keep small sample sizes of our products.
    However, since the anti-RGS2 antibody (ab36561) that you referenced has not been tested in mouse tissue, ...
