  • 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.
