Anti-SPC7 antibodies enable researchers to detect and measure the SPC7 antigen in biological samples. This target is a reported synonym of the PCSK7 gene, which encodes proprotein convertase subtilisin/kexin type 7. This protein is reported to be a serine endoprotease that processes various proproteins by cleavage at paired basic amino acids, recognizing the RXXX[KR]R consensus motif. The human version of SPC7 has a canonical amino acid length of 785 residues and a protein mass of 86.2 kilodaltons. It is reported to be localized in the Golgi of cells. SPC7 is a member of the Peptidase S8 protein family.
