Destabilization of DeltaNp63alpha by Nedd4-mediated ubiquitination and Ubc9-mediated sumoylation, and its implications on dorsoventral patterning of the zebrafish embryo.

Abstract excerpt

We have recently identified the p53-related DeltaNp63 gene as a transcriptional target of Bmp signaling that encodes a transcriptional repressor blocking neural development in the zebrafish ectoderm. However, in contrast to Bmps, the neural-repressing effect of forced DeltaNp63alpha expression is restricted to the presumptive forebrain, while posterior regions of the brain are not affected. Here, we show that...
