A novel p53-inducible gene, PAG608, encodes a nuclear zinc finger protein whose overexpression promotes apoptosis.
The biological effects of the p53 tumor suppressor protein are elicited, at least in part, through sequence-specific transactivation of a battery of target genes. The differential display method was employed towards identifying additional p53 target genes, with emphasis on genes whose induction may contribute to p53-mediated apoptosis. We report here the cloning of a novel p53-inducible gene, d...
متن کاملZinc Finger Protein Gene Complexes
Two murine homologs of the Drosophila Kriippel gene, a member of the gap class of developmental control genes that encode a protein with zinc fingers, were mapped to mouse chromosomes 8 and 11 by using somatic cell hybrids and an interspecific backcross. Surprisingly, both genes were closely linked to two previously mapped, Krtippelrelated zinc finger protein genes, suggesting that they are par...
متن کاملA new murine zinc finger gene, Opr
Here we report a novel murine zinc-finger gene, Opr, belonging to the opa/Zic family. Opr is expressed in the entire embryonic ectoderm before gastrulation, but gradually restricted to the anterior part from the mid to late streak stage. At the beginning of neural induction, Opr is expressed throughout the anterior neural plate, but is soon restricted to the neural ridge. After neural tube clos...
متن کاملSilencing of the tapetum-specific zinc finger gene TAZ1 causes premature degeneration of tapetum and pollen abortion in petunia.
TAZ1 (TAPETUM DEVELOPMENT ZINC FINGER PROTEIN1; renamed from PEThy; ZPT3-2) cDNA was first isolated as an anther-specific cDNA from petunia. Here, we report a functional characterization that includes analysis of spatial and temporal expression profiles and examination of anther phenotypes in TAZ1-silenced plants. TAZ1 showed a biphasic expression pattern. In the premeiotic phase, TAZ1 transcri...
متن کاملCys2/His2 zinc-finger protein family of petunia: evolution and general mechanism of target-sequence recognition.
The EPF family is a group of Cys2/His2zinc-finger proteins in petunia. In these proteins, characteristically long spacer regions have been found to separate the zinc fingers. Our previous DNA-binding studies demonstrated that two-fingered proteins (ZPT2-1 and ZPT2-2), which have spacers of different lengths, bind to two separate AGT core motifs in a spacing specific manner. To investigate the p...
