Lecture
This lecture covers the role of membrane binding domains in the PIP signaling pathway, focusing on the specific locations and signal-dependent turnover of PIPx species. It explains how proteins bind to cellular membranes, the activation of PLC, and the importance of PIPx in reversible membrane location and activation. The lecture also discusses different PIPx species recognition by domains, the abundance of PIP species, and the interactions with various PIPx species. Furthermore, it explores the significance of PH domains in recognizing Pl(3,4,5)P3 and the mechanisms of reversible membrane location and activation mediated by protein kinases and phospholipases.
