Epigenetics and chromatin in brain function

Mutations in genes encoding proteins that regulate chromatin structure are one of the most frequent causes of neurodevelopmental disorders, like Autism and Intellectual Disability. We still have very limited knowledge about how chromatin can impact brain function. The main goals of the Kramer lab are: 1) To learn more about the role of epigenetics and chromatin in regulation of learning and memory. 2) To understand the disease mechanisms associated with neurodevelopmental disorders that are caused by disrupted chromatin regulation. We are especially focused on epigenetic regulatory complexes involved in histone modification (acetylation/methylation) and ATP-dependent chromatin remodelling (SWI/SNF superfamily). We take a multidisciplinary systems approach, combining Drosophila behaviour, neuron specific transcriptomics and epigenomics, bioinformatics, developmental biology.
