Anti-PKHDL1 antibodies enable researchers to detect and measure the PKHDL1 antigen in biological samples. This target is a reported synonym of the PKHD1L1 gene, which encodes PKHD1 like 1. This protein is known to function in immune response pathways, among other biological roles. The human version of PKHDL1 has a canonical amino acid length of 4243 residues and a protein mass of 465.7 kilodaltons. It is reported to be localized in the membrane of cells.
