Napsin is a pepsin-like aspartic proteinase connected with maturation of surfactant protein B.
There are two closely related napsins, napsin A and napsin B.
Napsin A is expressed as a single chain protein.
Immunohistochemical studies revealed high expression levels of napsin A in human lung and kidney but low expression in spleen.
Napsin A is expressed in type II pneumocytes and in adenocarcinomas of lung.
The high specificity expression of napsin A in adenocarcinomas of lung is useful to distinguish primary lung adenocarcinomas from adenocarcinomas of other organs.
