  • Application notes
    Is unsuitable for ICC,IHC-P or IP.
  • Target

    • Function

      Guanine nucleotide-binding proteins (G proteins) are involved as modulators or transducers in various transmembrane signaling systems. The G(i) proteins are involved in hormonal regulation of adenylate cyclase: they inhibit the cyclase in response to beta-adrenergic stimuli. May play a role in cell division.
    • Sequence similarities

      Belongs to the G-alpha family. G(i/o/t/z) subfamily.
    • Cellular localization

      Cytoplasm. Cytoplasm > cytoskeleton > centrosome. Cell membrane. Localizes in the centrosomes of interphase and mitotic cells. Detected at the cleavage furrow and/or the midbody.
