Homeobox Genes and the Homeobox
Most homeobox [5] genes [4] contain a 180-base-pair region called a homeodomain [6]. The homeodomain [6] portion of the protein transcript has been shown to interact with DNA in a cisregulatory fashion during the critical stages of early body plan specification and embryogenesis [7]. These sorts of interactions demonstrate the importance of regulatory genes [4] and their architectural role in t...
متن کاملRhox: A New Homeobox Gene Cluster
Homeobox genes encode transcription factors notable for their ability to regulate embryogenesis. Here, we report the discovery of a cluster of 12 related homeobox genes on the X chromosome expressed in male and female reproductive tissues in adult mice. These reproductive homeobox on the X chromosome (Rhox) genes are expressed in a cell type-specific manner; several are hormonally regulated, an...
متن کاملQRX, a novel homeobox gene, modulates photoreceptor gene expression.
A novel paired-like homeobox gene, designated as Qrx, was identified by a yeast one-hybrid screen using the bovine Rhodopsin promoter Ret-1 DNA regulatory element as bait. Qrx is preferentially expressed in both the outer and inner nuclear layers of the retina. Its homeodomain is nearly identical to that of Rx/Rax, a transcription factor that is essential for eye development, but it shares only...
متن کاملNegative autoregulation of the Arabidopsis homeobox gene ATHB-2.
The Arabidopsis homeobox gene ATHB-2 is tightly regulated by light signals, and is thought to direct morphological changes during shade avoidance responses. To understand how ATHB-2 mediates light signals in plant morphogenesis, we investigated its transcriptional network. We constructed a gene encoding a chimeric transcription factor (HD-Zip-2-V-G) that is expected to activate target genes of ...
متن کاملExpression of the Optx2 homeobox gene during mouse development
Optx2, a member of the sine oculis-Six family of homeobox genes, is first expressed in the anterior neural plate of the mouse embryo, and subsequently in the optic vesicle and ventral forebrain. During later development, expression is further restricted to precursors of the neural retina, optic chiasm, adenohypophysis and neurohypophysis. In the adult mouse retina, Optx2 mRNA is found in cells ...
