Some potential mechanisms for finely-tuned regulation of phospholipase C-β isozymes : studies of dimerization and phosphatidylinositol 3,4,5-trisphosphate activation

Creator:

Zhang, Yong

Abstract:

Phospholipase C-β (PLC-β) isozymes are key effectors in G protein-coupled signaling pathways. Prior research suggested that some isoforms of PLC-β may exist and function as dimers, but little is known about dimerization of PLC-β. Data from coimmunoprecipitation assays of differentially-tagged PLC-β constructs and sizeexclusion chromatography of native PLC-β support homodimerization...

An emerging role for the exocyst : plant morphogenesis

Creator:

Cole, Rex A.

Abstract:

Plants develop a vast array of cell shapes and sizes by selectively modifying their surrounding cell walls to expand in some regions and not in others. This process of morphogenesis requires the delivery of secretory vesicles to specific locations at the cell periphery, where exocytosis adds new membrane and proteins...
