Anti-LPA1 antibodies enable researchers to detect and measure the LPA1 antigen in biological samples. This target is a reported synonym of the LPAR1 gene, which encodes lysophosphatidic acid receptor 1. This protein is known to function in brain development and GPCR signaling pathways, among other biological roles. The human version of LPA1 has a canonical amino acid length of 364 residues and a protein mass of 41.1 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the cell membrane of cells. Other names for this target antigen include EDG2 and Gpcr26.
