• Product name
    Anti-GNAI3 antibody [EPR11900]
    See all GNAI3 primary antibodies
  • Description
    Rabbit monoclonal [EPR11900] to GNAI3
  • Host species
  • Specificity
    The peptide immunogen shares a 94% and 93% homology with human GNAI1 and GNAI2 respectively, therefore we believe cross-reactivity is highly likely but this has not been experimentally assessed.
  • Tested applications
    Suitable for: Flow Cyt, IHC-P, WBmore details
    Unsuitable for: ICC/IF or IP
  • Species reactivity
    Reacts with: Mouse, Rat, Human
  • Immunogen

    Synthetic peptide within Human GNAI3 aa 300 to the C-terminus (C terminal). The exact sequence is proprietary.

  • Target

    • Function
      Guanine nucleotide-binding proteins (G proteins) are involved as modulators or transducers in various transmembrane signaling systems. G(k) is the stimulatory G protein of receptor-regulated K(+) channels. The active GTP-bound form prevents the association of RGS14 with centrosomes and is required for the translocation of RGS14 from the cytoplasm to the plasma membrane. May play a role in cell division.
    • Sequence similarities
      Belongs to the G-alpha family. G(i/o/t/z) subfamily.
    • Cellular localization
      Cytoplasm. Cell membrane. Cytoplasm > cytoskeleton > centrosome. Localizes in the centrosomes of interphase and mitotic cells. Detected at the cleavage furrow and/or the midbody.
