Background Information

Calpain 9 is also named as NCL4 and belongs to the peptidase C2 family.It can be down-regulated in gastric cancer tissue and in gastric cell lines of differentiated and poorly differentiated types.It is predominantly expressed in the gastrointestinal tract and restricted to the gastric surface mucus (pit) cells in the stomach and the function of it is implicated in suppressing tumorigenesis(PMID:20686710).
