Ready-to-use ELISA kits are available for the detection of GABA B Receptor 1, an alias of the protein, gamma-aminobutyric acid type B receptor subunit 1. The official gene symbol is GABBR1. The kits can detect several species variants of the protein, including: human, mouse, and rat. The protein, with a mass of 108.3 kDa and length of 961 residues, is reported to be membrane-associated and secreted. It is a member of the G-protein coupled receptor 3 family, GABA-B receptor subfamily and may be known by other names, including: GPRC3A, GABBR1-3, GABABR1, gamma-aminobutyric acid (GABA) B receptor 1, and GABA-B receptor R1 subunit.
