Anti-NEPH1 antibodies enable researchers to detect and measure the NEPH1 antigen in biological samples. This target is a reported synonym of the KIRREL1 gene, which encodes kirre like nephrin family adhesion molecule 1. This protein is known to function in cell adhesion, among other biological roles. The human version of NEPH1 has a canonical amino acid length of 757 residues and a protein mass of 83.5 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the cell membrane of cells and notably expressed in the kidney. Other names for this target antigen include KIRREL and KIRREL.
