| Background Information | The Gβ5 (GNB5 guanine nucleotide binding protein (G protein), beta 5) is a G protein subunit present predominantly in the central nervous system. This protein appears to be expressed in two forms, one found in the brain of 39 kDa and one found in the retina of 44 kDa. It has also been found that Gβ5 associates tightly with RGS7, a member of the superfamily of negative regulators of G protein signaling. These complexes have been localized to most regions of the brain, whereas Gβ1-4 exhibit no observable colocalization with RGS7, despite their widespread codistribution throughout similar neuronal networks. This antibody is specific for a peptide sequence within the D1 blade which is not found in Gβ1-4. |

| Application Notes | Western Blotting Analysis: A representative lot detected Gβ5 in HA-ERK2, HA-MAPK, and Gβ5 in cotransfected COS cells, cholate membrane extracts of control (Con) or transfected (b5 1 g2) COS cells, mouse, or bovine brain (Zhang, S., et al. (1996). JBC. 271(52):33575-33579). Western Blotting Analysis: A representative lot detected Gβ5 in PC12 and mouse brain, and PC12 cells transiently transfected with GFP fusion constructs (Zhang, S., et al. (2001). JBC. 276(13):10284-10289). Western Blotting Analysis: A representative lot detected Gβ5 in PC12 transfected with fusion proteins, brains of wild-type, R7 binding protein (R7BP), and knockout (KO) mice (Leelamma, M.P., et al. (2010). Journal of Neurochemistry. 113:1101-1112). Immunocytochemistry Analysis: A representative lot detected Gβ5 in NGF-differentiated PC12 cells, NGF-differentiated PC12 cells stably transfected with pTREHAGb5 encoding HA epitope-tagged Gb5 were induced with doxycycline (Zhang, S., et al. (2001). JBC. 276(13):10284-10289). Immunocytochemistry Analysis: A representative lot detected Gβ5 in PC12 cells transfected with the cDNA combinations HA-Gb5/RGS7HA-Gb5/DRGS-RGS7, or HA-Gb5/Depless-RGS7, Neuro-2A or SH-SY5Y cells transfected with the HAGb5/RGS7 or HA-Gb5/Depless-RGS7 (Leelamma, M.P., et al. (2010). Journal of Neurochemistry. 113:1101-1112). Immunofluorescence Analysis: A representative lot detected Gβ5 in primary cortical neuronal cells derived from wild-type and R7 binding protein (R7BP) homozygous knockout (KO) mice (Leelamma, M.P., et al. (2010). Journal of Neurochemistry. 113:1101-1112). |
