Anti-GPR45 antibodies are used in the immunodetection of the protein G protein-coupled receptor 45. In humans, the canonical protein has a reported length of 372 amino acid residues and a mass of 42 kDa. Its subcellular localization is in the cell membrane. It is reported to be expressed in the brain; detected in the basal forebrain, frontal cortex, and caudate, but not in thalamus, hippocampus, or putamen. A member of the G-protein coupled receptor 1 protein family, GPR45 is categorized as a type of orphan receptor. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include PSP24(ALPHA), PSP24A, probable G-protein coupled receptor 45, PSP24-1, PSP24-alpha, and PSP24. GPR45 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish and chimpanzee species. Western Blot is a widely used application for the GPR45 antibodies listed below. In addition, Immunohistochemistry is also a common application.
