The GB1 ELISA kits listed below are analytical tools for measuring concentrations of GB1 in various samples. GB1 is an alternative name for the human GABBR1 gene, which encodes the protein, gamma-aminobutyric acid type B receptor subunit 1. It has been mentioned that GB1 plays a role in the regulation of cell proliferation and osteoblast differentiation, among other functions. Structurally, the GABBR1 protein is 961 amino acid residues in length and 108.3 kilodaltons in mass. However, as many as 5 protein isoforms have been identified. It is localized to the cell membrane of the cell. In terms of tissue specificity, it is reported to be highly expressed in the brain. This protein is known to be glycosylated. Other names for this target antigen include GABABR1, GABABR1, and GABBR1-3. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
