WebOct 24, 2024 · We readily identified proteins of the cystatin family, a group of cysteine proteases of ~16 kD, because they increased markedly with exercise, and are much smaller proteins than amylase. Previous studies have reported cystatins as a product primarily of submandibular glands, while amylase is derived mainly from parotid glands [ 13 ]. WebSep 7, 2012 · CC9 belongs to cluster I, which contains only cystatins of the two monocotyledonous plants, while the clusters II and III contain cystatins of all three organisms. The closest homolog of CC9 is CC12, which shows 53% sequence identity but does not contain a predicted secretion signal.
