  • FunctionGuanine 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 similaritiesBelongs to the G-alpha family. G(i/o/t/z) subfamily.
  • Cellular localizationCytoplasm. Cytoplasm > cytoskeleton > centrosome. Cell membrane. Localizes in the centrosomes of interphase and mitotic cells. Detected at the cleavage furrow and/or the midbody.

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 ...
