GENE INFORMATION
Gene name	NAPSA (HGNC Symbol)
Synonyms	KAP, Kdap, NAP1, NAPA
Description	Napsin A aspartic peptidase (HGNC Symbol)
Entrez gene summary	The activation peptides of aspartic proteinases plays role as inhibitors of the active site. These peptide segments, or pro-parts, are deemed important for correct folding, targeting, and control of the activation of aspartic proteinase zymogens. The pronapsin A gene is expressed predominantly in lung and kidney. Its translation product is predicted to be a fully functional, glycosylated aspartic proteinase precursor containing an RGD motif and an additional 18 residues at its C-terminus.
