We found 15–30% of total cellular DGK-ζ in the nucleus both of COS-7 cells transfected with DGK-ζ complementary DNA and of A172 cells, a glioblastoma-derived line, which express native DGK-ζ . 2007-01-01 · Pellet nuclei at 650g for 5 min. Resuspend the final nuclear pellet in desired buffer and proceed to DGK assays described earlier. Further fractionation of the nuclei can be achieved using protocols that have been described ( Ledeen and Wu, 2004 ). ABSTRACT The nucleus contains diacylglycerol ki-nases (DGKs), i.e., the enzymes that, by converting diacylglycerol (DG) into phosphatidic acid, terminate DG-dependent events.

Western blots demonstrated that DGK-theta was enriched in the nuclear matrix fraction prepared from MDA-MB-453 cells.

A, COS-7 cells transfected with human DGK in an expression vector express a 130-kDa protein. The nucleus contains diacylglycerol kinases (DGKs), i.e., the enzymes that, by converting diacylglycerol (DG) into phosphatidic acid, terminate DG‐dependent events.It has been demonstrated that nuclear DGK‐ζ interferes with cell cycle progression. We previously reported that nuclear DGK‐ζ expression increased during myogenic differentiation, whereas its down‐regulation impaired DGK-ζ also displays a functional independent nuclear export signal (NES) sequence between the amino acid residues 362-370. Mutation of DGK-ζ NES was performed by replacing leucines with alanines using site-directed mutagenesis.

Previous reports have shown that the nucleus contains diacylglycerol kinases (DGKs), i.e., the enzymes that, by converting DAG into phosphatidic acid (PA), terminate DAG-dependent events. DGK-ζ export from nucleus to cytoplasm is regulated by a leucine-rich NES through the exportin CRM1 and suggest that the nuclear localization of DGK-ζ could finely tune its function as a regulator of G 1 /S cell cycle transition.

HeLa and PC12 cells showed some DGK-θ staining in the cytoplasm, whereas in MDA-MB-453 and MCF-7 cells cytoplasmic positivity was almost undetectable. In biochemical assays, the C terminus of DGK-zeta, which contains a consensus PDZ-binding motif, was found to be necessary and sufficient for association with gamma 1-syntrophin. When coexpressed in HeLa cells, DGK-zeta and gamma 1-syntrophin formed a stable complex that partitioned between the cytoplasm and nucleus.
