Anti-Brain-Specific Angiogenesis Inhibitor 1 antibodies are used in antigen-specific immunodetection in biological samples. The target Brain-Specific Angiogenesis Inhibitor 1 is a known alias name of the protein adhesion G protein-coupled receptor B1, encoded by the ADGRB1 gene in humans. This 1584-amino acid residue protein is reported to be a phosphatidylserine receptor, which enhances the engulfment of apoptotic cells. It is localized to the cell membrane and is secreted of the cell and features glycosylated, ubiquitinated and cleaved post-translational modifications. In terms of tissue expression, it is notably expressed in the brain. Other synonyms for Brain-Specific Angiogenesis Inhibitor 1 include BAI1, BAI1, and GDAIF.
