Inositol phosphate-containing molecules play an important role in a broad range of cellular processes. Inositol 5-phosphatases participate in the regulation of these signaling molecules. We have identified four inositol 5-phosphatases in Dictyostelium discoideum, Dd5P1-4, showing a high diversity in domain composition. Dd5P1 possesses only a inositol(More)
BACKGROUND Treatment with atypical antipsychotic agents is often complicated by dyslipidemia, which is a risk factor for cardiovascular disease. OBJECTIVES To determine whether the LEPR Q223R, the LEP -2548G/A, and the HTR2C -759C/T polymorphisms are associated with dyslipidemia in patients using atypical antipsychotic drugs. METHODS A cross-sectional(More)
Polymorphisms in genes coding for drug metabolizing enzymes, such as the cytochrome P450 enzymes CYP2C19 and CYP2D6, can lead to therapy failure and side effects. In earlier studies, the novel variant CYP2C19*17 increased metabolism of several CYP2C19 substrates. The objective of this study was to evaluate the impact of CYP2C19*17 on the metabolism of(More)
Prescription of clozapine is complicated by the occurrence of clozapine-induced reduction of neutrophils. The aim of this study was to identify genetic risk factors in a population of 310 Dutch patients treated with clozapine, including 38 patients developing neutropenia and 31 patients developing agranulocytosis. NQO2 1541AA (NRH quinone oxidoreductase 2;(More)
DdGCA is a Dictyostelium guanylyl cyclase with a topology typical for mammalian adenylyl cyclases containing 12 transmembrane-spanning regions and two cyclase domain. In Dictyostelium cells heterotrimeric G-proteins are essential for guanylyl cyclase activation by extracellular cAMP. In lysates, guanylyl cyclase activity is strongly stimulated by guanosine(More)
