Our major research focus has the objective of understanding phosphoinositide (PI) and inositol phosphate signal transduction pathways that impact cellular regulatory events. All eukaryotic cells are regulated by phosphoinositide signals. In phosphoinositide signaling, PI, a phospholipid, is sequentially phosphorylated on the inositol ring to form essential signaling molecules such phosphatidylinositol-4,5-bisphosphate (PI4,5P2). PI4,5P2 is directly synthesized by phosphatidylinositol-phosphate kinases (PIPKs), and PI4,5P2 occupies an essential position in PI signaling by directly regulating cellular functions that include cell proliferation, secretion, cytoskeletal assembly and cell motility. In addition, PI4,5P2 is a key transducer of cellular signals as a precursor for many second messengers. The PIPKs define an enzyme superfamily responsible for the generation of all PI derived second messengers, demonstrating that these kinases have roles in many cellular functions. The different PIPK family members are targeted to subcellular compartments by specific protein-protein interactions. The interactions between the PIPKs and targeting proteins results in spatial and temporal generation of PI4,5P2 that regulates specific cellular functions.  Lab
