Our lab studies gene regulation in germ cells, with a focus on “RNA granules” which are phase-separated compartments rich in RNA and proteins. We have identified a family of intrinsically-disordered proteins that form gel-like assemblies that sequester RNA (RNA...
Eukaryotic cells package their genomes in the form of chromatin, which is comprised of histone proteins and DNA. Modification of chromatin by chemical marks such as methylation and acetylation affects how cellular machineries interpret the genome. The Taverna laboratory...
We study the structure and function of the cell nucleus, ‘mothership’ of the human genome. We seek to understand how nuclear envelope (NE) membrane proteins interact with nuclear intermediate filament (‘lamina’) networks and other partners to collectively establish, protect...
Protein function is dynamically regulated in the cell by reversible posttranslational modifications. We are interested in the mechanism by which chromatin modifications regulate transcription, nucleosome dynamics and the response to DNA damage. A particular focus is on the non-degradative...
Organisms go through cycles of metabolic activity, driven by internal cues (circadian, circannual clocks) and physiologic/behavioral inputs (e.g. feeding/fasting, physical activity/rest). In addition, organisms face environmental challenges (physical, chemical or psychological stressors) that require continual adaptation of the pathways...
We study how epithelial tubular organs – which are essential to life in all multicellular organisms – form and specialize. Using the simple unbranched tubes of the Drosophila salivary gland and the beautifully branched tubular network of the Drosophila...
The goal of the Meffert lab is to gain a mechanistic understanding of how selective gene programs are recruited and maintained to modify the nervous system during development, experience-dependent plasticity, and in injury or disease. Rather than focusing on...
My laboratory is interested in the molecular mechanisms by which cells interpret signals from their environment that instruct them to proliferate, differentiate, or die by apoptosis. This process is of fundamental importance in the development and function of the...
CRISPR-Cas loci serve as acquired immune systems which protect their bacterial and archaeal hosts from viruses and plasmids. CRISPR immunity occurs in two phases: First, short DNA segments from foreign invaders are captured and inserted into the CRISPR locus...
