Napsin A is a pepsin-like aspartate protease with a molecular weight of about 38 kDa. Napsin A is closely related to Napsin B. Napsin is expressed as a single-chain protein in type II pneumocytes and in adenocarcinomas of the lung and kidney. The high specificity of Napsin A in lung adenocarcinomas is useful in distinguishing such primary adenocarcinomas from adenocarcinomas of unknown origin.
