Abstract
Protein kinase C γ (PKC γ) is a brain-specific isozyme expressed at a high level in the adult but not in the fetal or newborn rat. At least seventeen nuclear protein binding sites within the 5'-flanking region extending from -1612 to +243 had been identified by DNase I footprinting analysis and gel mobility shift assays. Among them, one site, GAATTAATAGG, at -669 to -679 is protected from DNase I digestion by nuclear protein from newborn but not from the adult rat brain. The levels of this binding protein, as determined by gel mobility shift assay, were found inversely related to the levels of PKC γ in rat brain at different stages of development. These results suggest that this particular binding site may participate in the developmental regulation of PKC γ gene.
