Anti-NKRP1 antibodies enable researchers to detect and measure the NKRP1 antigen in biological samples. This target is a reported synonym of the KLRB1 gene, which encodes killer cell lectin like receptor B1. This protein is known to function in receptor-mediated signaling pathways, among other biological roles. The human version of NKRP1 has a canonical amino acid length of 225 residues and a protein mass of 25.4 kilodaltons. It is reported to be localized in the membrane of cells and widely expressed in many tissue types. Other names for this target antigen include CD161, CD161, and CLEC5B.
