Msp／RonReceptorSignalingPathway
MSP, macrophage-stimulating protein, acts through the transmembrane receptor kinase RON (Stk in mice) to play a role in inflammation and the response to tissue injury. MSP is secreted by the liver into the blood as pro-MSP, an inactive precursor form. MSP is related to clotting factors that are activated by proteolytic cleavage and pro-MSP is itself also activated by cleavage to MSP. Binding of activated MSP heterodi......阅读全文
