| Research Abstract |
Results show that stratal medium spiny neurons of DGKb-KO mice exhibit reduced dendritic spine density at the distal dendrites compared with wild-type mice. We also sought protein targets that interact with DGKb and identified the GluR2 AMPA receptor subunit as a novel DGKb binding partner. DGKe immunoreactivity was widely distributed in the cerebellulm. At higher magnifications, DGKe was detected as granular structure in Purkinje cells (PCs) dendrites and perikarya. Ultrastructural localization of DGKe was examined in PCs by pre-embedding immunoelectron microscopy, showing that DGKe-immunoreactivities were distributed in flattened or tubular smooth endoplasmic reticulum just under the cell membrane, which were presumed subsurface cisterns. In rat adrenal gland,RT-PCR analysis showed that the expression signals for DGKb and DGKe are intensely detected. At protein level, DGKb was not expressed in the adrenal gland, but DGKe was detected on the plasma membrane in the zone glomerulosa.
