Anti-WFIKKNRP antibodies enable researchers to detect and measure the WFIKKNRP antigen in biological samples. This target is a reported synonym of the WFIKKN2 gene, which encodes WAP, follistatin/kazal, immunoglobulin, kunitz and netrin domain containing 2. This protein is known to function in skeletal system development, among other biological roles. The human version of WFIKKNRP has a canonical amino acid length of 576 residues and a protein mass of 63.9 kilodaltons. It is reported to be a secreted protein. WFIKKNRP is a member of the WFIKKN protein family.
