Anti-gamma-aminobutyric acid type A receptor subunit epsilon antibodies are used for the immunodetection of the protein encoded by the GABRE gene. In humans, the canonical protein has a reported length of 506 amino acid residues and a mass of 58 kDa. Its subcellular localization is in the cell membrane. Alternative splicing is reported to yield 2 different isoforms for this protein. It is reported to be expressed in many tissues. A member of the Ligand-gated ion channel (TC 1.A.9) protein family, it is known to be involved with signal transduction pathways. Post-translational modifications have been described, including glycosylation. Other names for this target antigen include GABA(A) receptor subunit epsilon, GABA(A) receptor, epsilon, gamma-aminobutyric acid (GABA) A receptor, epsilon, and gamma-aminobutyric acid receptor subunit epsilon. Gene orthologs have been identified in the mouse, rat, bovine, chimpanzee and chicken species.
