Molecular Mechanisms

Stephanie Bielas plans to study an Asxl3 null mouse model to better understand the role that Asxl3-dependent deubiquitination activity plays in specifying neural progenitor cell transcriptional programs that regulate cortical neuronal fate.

Mutations in the FMR1 gene, which encodes the RNA-binding protein FMRP, are the most common cause of intellectual disability and autism spectrum disorder. In the current project, Ethan Greenblatt plans to leverage the genetically and biochemically tractable Drosophila oocyte system to understand the mechanism of FMRP-dependent translation. Such knowledge will help advance the development of novel diagnostics and therapies for ASD subtypes that are caused by haploinsufficiency of FMRP or downstream targets.
