These LPA1 ELISA kits are immunodetection tools for measuring the levels of LPA1 in biological samples. LPA1 is an alias name of the human LPAR1 gene, which encodes the protein, lysophosphatidic acid receptor 1. Notably, LPA1 is known to play a role in brain development and GPCR signaling pathways, among other functions. The LPAR1 protein is 364 amino acid residues in length and 41.1 kilodaltons in mass. However, as many as 2 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 expressed in many adult organs, including brain, heart, colon, small intestine, placenta, prostate, ovary, pancreas, testes, spleen, skeletal muscle, and kidney. This protein is known to be N-glycosylated. Other names for this target antigen include EDG2 and Gpcr26.
