Anti-guanine nucleotide binding protein (G protein), gamma 5 antibodies are used in antigen-specific immunodetection in biological samples. The target guanine nucleotide binding protein (G protein), gamma 5 is a known alias name of the protein G protein subunit gamma 5, encoded by the GNG5 gene in humans. This 68-amino acid residue protein is known to be involved in GPCR signaling pathways, among other biological processes. It is localized to the cell membrane of the cell. It is reported to be widely expressed in many tissue types. Other synonyms for guanine nucleotide binding protein (G protein), gamma 5 include guanine nucleotide-binding protein G(I)/G(S)/G(O) subunit gamma-5 and guanine nucleotide binding protein (G protein), gamma 5.
