The Boag lab is primarily interested in understanding how post transcriptional gene regulation influences development and cellular function. In a number of cell types, such as oocytes and neurons, many mRNAs are transcribed but are not immediately translated. Instead, these mRNAs are maintained in a translationally repressed state in predicted RNA-protein storage granules and only become translated upon specific cues. Some of the proteins involved in the storage of oocyte mRNAs are also present in Processing-bodies (P-bodies), recently identified cytoplasmic granules where many mRNA regulatory pathways are present, including decapping- and nonsense-mediated mRNA degradation and small RNA-mediated translational silencing (e.g. micro RNAs). The emerging similarities between germline storage granules and P-bodies suggests that the formation of RNA-protein granules is a conserved and important mechanism for maintaining cellular homeostasis. We are interested in elucidating the mechanisms governing the formation and function of germline mRNA storage granules and their requirement for fertility and embryonic viability.
