  • 機能
    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.
  • 配列類似性
    Belongs to the G-alpha family. G(i/o/t/z) subfamily.
  • 細胞内局在
    Cytoplasm. Cytoplasm > cytoskeleton > centrosome. Cell membrane. Localizes in the centrosomes of interphase and mitotic cells. Detected at the cleavage furrow and/or the midbody.

レビューと Q&A

Thank you for sending the image again.

As my colleague mentioned you may need to increase the denaturing and reducing conditions with this specific cell line.

My suggestion is to lysate the cells with RIPA buffer, a recipe for this ...

Thank you for your inquiry.

I am sorry to hear that you are getting results that are hard to interpret.

I believe the 120kDa band is not a complex containing G protein alpha Inhibitor 2 since you are using denaturing and reducing co...
