SP_COMMENT cofactor:Magnesium., domain:The basic-rich region is essential for yopT recognition and cleavage., function:Regulates a signal transduction pathway linking plasma membrane receptors to the assembly of focal adhesions and actin stress fibers. Serves as a target for the yopT cysteine peptidase from Yersinia pestis, vector of the plague, and Yersinia pseudotuberculosis, which causes gastrointestinal disorders. May be an activator of PLCE1. Activated by ARHGEF2, which promotes the exchange of GDP for GTP., PTM:Cleaved by yopT protease when the cell is infected by some Yersinia pathogens.
