Research Abstract

SAP-1 is a receptor-type protein tyrosine phosphatase that specifically localizes to microvilli of the brush border in gastrointestinal epithelial cells. In this study, I found that SAP-1 and p100 interact through their ectodomains and form a complex. I also found that SAP-1/p100 regulates the production of chemokine and the phagocytosis of HEK293 cells, suggesting intestinal immunity might be regulated by these physiological functions of SAP-1/p100.
