Control of imaginal cell development by the escargot gene of Drosophila.
Mutations in the escargot (esg) locus, which codes for a zinc-finger-containing protein with similarity to the product of the snail gene, cause a variety of defects in adult structures such as loss of abdominal cuticle and malformation of the wings and legs. esg RNA is expressed in wing, haltere, leg and genital imaginal discs and in abdominal histoblast nests in the embryo. Expression in imagi...
متن کاملIdentification of a novel transcriptional repressor encoded by human cytomegalovirus.
The expression of human cytomegalovirus (HCMV) genes during viral replication is precisely regulated, with the interactions of both transcriptional activators and repressors determining the level of gene expression. One gene of HCMV, the US3 gene, is transcriptionally repressed early in infection. Repression of US3 expression requires viral infection and protein synthesis and is mediated throug...
متن کاملDrosophila CRYPTOCHROME Is a Circadian Transcriptional Repressor
BACKGROUND Although most circadian clock components are conserved between Drosophila and mammals, the roles assigned to the CRYPTOCHROME (CRY) proteins are very different: Drosophila CRY functions as a circadian photoreceptor, whereas mammalian CRY proteins (mCRY1 and 2) are transcriptional repressors essential for molecular clock oscillations. RESULTS Here we demonstrate that Drosophila CRY ...
متن کاملEstablishment of Drosophila imaginal precursor cells is controlled by the Arrowhead gene.
Metamorphosis in Drosophila melanogaster requires synchronization of numerous developmental events that occur in isolated imaginal precursor tissues. The imaginal primordia are established during embryonic stages and are quiescent for much of larval life. The Arrowhead gene is necessary for establishment of proper numbers of cells within a subset of imaginal precursor tissues. Loss-of-function ...
