Background: Cystatin SN

Cystatin SN is a member of family 2 of the cystatin superfamily (1). Together with cystatins S and SA, it is produced by the salivary gland and secreted largely in the submandibular/sublingual saliva (2). Cystatin SN inhibits members of the papain family including cathepsins B, C, H and L (3).
