Background

Napsin is a pepsin-like aspartic proteinase, in the A1 clan of the AA clade of proteinases. Other AA family proteinases include Pepsin, cathepsin-D, cathepsin-E and rennin. Of these proteinases, napsin is most closely related to cathepsin-D, sharing 46% identity at the amino acid level. There are two closely related Napsins, napsin A and napsin B, with 85% overall identity at the amino acid level. There are three isoforms. Napsin-A is also termed napsin-1, or TA02, a Tumor Adenocarcinoma marker. Napsin A may be involved in processing of pneumocyte surfactant precursors.
