Anti-VR-1 antibodies enable researchers to detect and measure the VR-1 antigen in biological samples. This target is a reported synonym of the TRPV1 gene, which encodes transient receptor potential cation channel subfamily V member 1. This protein is known to function in receptor-mediated signaling pathways and TNF-mediated cellular signaling pathways, among other biological roles. The human version of VR-1 has a canonical amino acid length of 839 residues and a protein mass of 95 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the cell membrane of cells. VR-1 is a member of the Transient receptor (TC 1.A.4) protein family.
