  • Relevance

    GABA is the major inhibitory neurotransmitter in the vertebrate brain and mediates neuronal inhibition by binding to the gaba/benzodiazepine receptors and opening an integral chloride channel. GABRR2 is a member of the rho subunit family of GABA receptors and could play a role in retinal neurotransmission.
  • Cellular localization

    Cell junction > synapse > postsynaptic cell membrane; Multi-pass membrane protein. Cell membrane; Multi-pass membrane protein.

  • ICC/IF image of ab83223 stained SKNSH cells. The cells were 100% methanol fixed (5 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab83223, 1µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899, DyLight® 488 goat anti-rabbit IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM
