These ASRT1 ELISA kits are immunodetection tools for measuring the levels of ASRT1 in biological samples. ASRT1 is an alias of the human PTGDR gene, which encodes the protein, prostaglandin D2 receptor. Notably, ASRT1 is known to play a role in GPCR signaling pathways and inflammatory response pathways, among other functions. The PTGDR protein is 359 amino acid residues in length and 40.3 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 retinal choroid, ciliary epithelium, longitudinal and circular ciliary muscles, iris, small intestine and platelet membranes. This protein is known to be glycosylated. Other names for this target antigen include AS1 and DP.
