| Research Abstract |
It was shown that PSTPIP2 is a negative regulator of phagocytosis. It is suggested that PSTPIP2 is localized to the nascent cup, where it suppress the robust actin polymerization. The localization of PSTPIP2 to the nascent cup is dependent on its lipid binding ability. In addition, PSTPIP2 is tyrosine phosphorylated following phagocytosis and its phosphorylation dissociates it from the nascent cup. Thus, PSTPIP2 is the novel negative regulator of phagocytosis though inhibiting phagocytic cup formation that is controlled by its tyrosine phosphorylation.
