Anti-G Protein-coupled Receptor antibodies enable researchers to detect and measure the G Protein-coupled Receptor antigen in biological samples. This target is a reported synonym of the ADRA1A gene, which encodes adrenoceptor alpha 1A. This protein is known to function in pathways of aging and the apoptotic pathway, among other biological roles. The human version of G Protein-coupled Receptor has a canonical amino acid length of 466 residues and a protein mass of 51.5 kilodaltons, although 9 isoforms have been identified. It is reported to be localized in the cell membrane, nucleus, and cytoplasm of cells and notably expressed in the hippocampus, cerebral cortex, and caudate. Other names for this target antigen include ADRA1C, ADRA1L1, and ALPHA1AAR. Some G Protein-coupled Receptor antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
