Anti-GABBR1 antibodies are used in the immunodetection of the protein gamma-aminobutyric acid type B receptor subunit 1. In humans, the canonical protein has a reported length of 961 amino acid residues and a mass of 108.3 kDa. Its subcellular localization is in the cell membrane. Up to 5 different isoforms have been reported for this protein. It is reported to be highly expressed in the brain. A member of the G-protein coupled receptor 3 protein family, GABBR1 is a known component of the heterodimeric G-protein coupled receptor for GABA, formed by GABBR1 and GABBR2. Synonyms for this target antigen include GABBR1-3, GB1, GPRC3A, GABA-B receptor, R1 subunit, gamma-aminobutyric acid (GABA) B receptor, 1, and GABABR1. GABBR1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish and chimpanzee species. A number of GABBR1 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. Immunofluorescence and Immunohistochemistry are also common applications.
