Regulating Glut4 vesicle dynamics by phosphoinositide kinases and phosphoinositide phosphatases.
Phosphorylated derivatives of phosphatydylinositol (PtdIns), collectively called phosphoinositides (PIs), have been recognized as versatile second messengers and modulators of lipid membrane composition in all eukaryotes. Over the last several years, PIs emerged as key membrane-localized signals for regulating a myriad of cellular processes, including insulin-induced membrane receptor signaling...
متن کاملBiochemistry and structure of phosphoinositide phosphatases
Phosphoinositides are the phosphorylated derivatives of phosphatidylinositol, and play a very significant role in a diverse range of signaling processes in eukaryotic cells. A number of phosphoinositide-metabolizing enzymes, including phosphoinositide-kinases and phosphatases are involved in the synthesis and degradation of these phospholipids. Recently, the function of various phosphatases in ...
متن کاملPhosphoinositide phosphatases: emerging roles as voltage sensors?
During a genomic survey of the transparent sea squirt (Ciona intestinalis), Murata et al. discovered a gene that encodes a protein containing homologous sequences to both a CX(5)R phosphatase and an ion channel. The authors named the novel protein, C. intestinalis voltage-sensor-containing phosphatase, Ci-VSP. The N terminus of Ci-VSP appears to function as a voltage-gated sensor; the C terminu...
متن کاملBiology of TH17 Lymphocytes, their Cytokines and Role in Disease
T lymphocytes that are involved in cellular mediated immunity include two types known as TCD8+ (Cytotoxic T lymphocytes) and TCD4+ (helper T lymphocytes). TCD4+ has four main subtypes, including TH1, TH2, TH17, and Treg Lymphocytes.TH17 lymphocytes play a role in defense against microbes that TH1 and TH2 lymphocytes have not the ability to respond to them. The most important cytokines, which ar...
متن کاملRegulation of phosphoinositide signaling by the inositol polyphosphate 5-phosphatases.
Phosphoinositide signaling molecules control cellular growth, proliferation and differentiation, intracellular vesicle trafficking, and cytoskeletal rearrangement. The inositol polyphosphate 5-phosphatase family remove the D-5 position phosphate from PtdIns(3,4,5)P3, PtdIns(4,5)P2 and PtdIns(3,5)P2 forming PtdIns(3,4)P2, PtdIns(4)P and PtdIns(3)P respectively. This enzyme family, comprising ten...
