Rett syndrome (RTT) is a debilitating neurological condition associated with mutations in the X-linked MECP2 gene, where apparently normal development is seen prior to the onset of cognitive and motor deterioration at 6-18 months of life. A targeted deletion of the methyl-CpG-binding domain (MBD) coding region and disruption of mRNA splicing was introduced(More)
Rhou encodes a Cdc42-related atypical Rho GTPase that influences actin organization in cultured cells. In mouse embryos at early-somite to early-organogenesis stages, Rhou is expressed in the columnar endoderm epithelium lining the lateral and ventral wall of the anterior intestinal portal. During foregut development, Rhou is downregulated in regions where(More)
Cytidine (C) to Uridine (U) RNA editing is a post-transcriptional modification that is accomplished by the deaminase APOBEC1 and its partnership with the RNA-binding protein A1CF. We identify and characterise here a novel RNA-binding protein, RBM47, that interacts with APOBEC1 and A1CF and is expressed in tissues where C to U RNA editing occurs. RBM47 can(More)
Krüppel-like factors 3 and 8 (KLF3 and KLF8) are highly related transcriptional regulators that bind to similar sequences of DNA. We have previously shown that in erythroid cells there is a regulatory hierarchy within the KLF family, whereby KLF1 drives the expression of both the Klf3 and Klf8 genes and KLF3 in turn represses Klf8 expression. While the(More)
Rbm47 encodes a RNA binding protein that is necessary for Cytidine to Uridine RNA editing. Rbm47(gt/gt) mutant mice that harbor inactivated Rbm47 display poor viability. Here it was determined that the loss of Rbm47(gt/gt) offspring is due to embryonic lethality at mid-gestation. It was further showed that growth of the surviving Rbm47(gt/gt) mutants is(More)
We are using knockdown of gene expression in mouse embryos by constitutive expression of small hairpin (sh)RNAs as a means of observing loss-of-function phenotypes more rapidly than gene targeting. Plasmid constructs that direct shRNA expression via an RNA pol III promoter are introduced into embryonic stem (ES) cells by electroporation and drug selection.(More)
