The role of PIP5K family kinases in plasma membrane remodeling
Apolínová, Kateřina ; Macůrková, Marie (advisor) ; Lišková, Petra (referee)
Phosphatidylinositol 4-phosphate 5-kinase (PIP5K) is the enzyme responsible for the production of phosphatidylinositol 4,5-bisphosphate (PI(4,5)P2), which has long been known as a precursor of two important second messengers, diacylglycerol and inositol trisphosphate. However, PI(4,5)P2 also acts as a second messenger in its own right and regulates many processes occurring on the plasma membrane such as endo- and exocytosis, actin cytoskeleton remodeling, and the formation of cell-cell contacts. The action of PIP5K is carefully spatially and temporally regulated in order to form localized pools of PI(4,5)P2 crucial for its many roles in a wide variety of cell processes. This bachelor's thesis focuses on the description of regulatory mechanisms that control PIP5K activity in vivo and on its physiological functions at the plasma membrane.
