Summary
Predicted to enable aspartic-type endopeptidase activity. Predicted to be involved in membrane protein proteolysis and surfactant homeostasis. Predicted to be located in alveolar lamellar body. Predicted to be active in extracellular space and lysosome. Orthologous to human NAPSA (napsin A aspartic peptidase). [provided by Alliance of Genome Resources, Nov 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
