Anti-NPSR antibodies enable researchers to detect and measure the NPSR antigen in biological samples. This target is a reported synonym of the NPSR1 gene, which encodes neuropeptide S receptor 1. This protein is known to function in the regulation of the ERK1 and ERK2 signaling cascade, among other biological roles. The human version of NPSR has a canonical amino acid length of 371 residues and a protein mass of 42.7 kilodaltons, although 9 isoforms have been identified. It is reported to be localized in the cell membrane and cytoplasm of cells. NPSR is a member of the G-protein coupled receptor 1 protein family. Indicated applications for NPSR antibodies listed below include ELISA and Western Blot.
