General description

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.

Immunogen

Epitope: C-terminus
KLH-conjugated linear peptide corresponding to the C-terminus of human Gβ5.

Application

Quality

Evaluated by Western Blotting in mouse brain tissue lysate.

Western Blotting Analysis: A 1:500 dilution of this antibody detected Gβ5 in 10 µg of mouse brain tissue lysate.

Target description

~39 kDa observed. Uniprot describes 3 isoforms produced by alternative splicing at ~44 kDa, ~39 kDa, and ~31 kDa and this antibody is predicted to cross-react with all three.

Physical form

Rabbit polyclonal serum with 0.05% sodium azide.
Unpurified

Storage and Stability

Stable for 1 year at -20°C from date of receipt.
Handling Recommendations: Upon receipt and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20°C. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance.

While multiple G protein beta and gamma subunit isoforms have been identified, the implications of this potential diversity of betagamma heterodimers for signaling through betagamma-regulated effector pathways remains unclear. Furthermore the molecular mechanism(s) by which the betagamma complex modulates diverse
