Research Focus 
The mechanism of mRNA transport and localised translation in Drosophila. We are elucidating the cis-acting RNA signals and transacting factors that dictate the intracellular destination of mRNA and its localised translation in oocytes and neuromuscular junctions. 


Keywords:  RNA, Development, Drosophila, live cell imaging,  synaptic plasticity, neuromuscular junction



We welcome informal enquiries from prospective Post-Doc (email darragh.ennis@bioch.ox.ac.uk) and PhD students (click here)






Cells are the fundamental unit of all life on earth. Understanding how cells function is a major goal of modern biology and is of major importance in medicine. Our lab is using flies as a model system to understand how molecules are actively sorted and distributed within cells. We are working to better understand how the growth and development of nerves is regulated. Furthermore, flies are an excellent model for many human diseases, including genetic disorders and infections.

Localisation of gurken RNA injected into Drosophila egg chamber

Video by Kirsty Gill & Richard Parton
We use fluorescent proteins to track the movement of RNA through Drosophila, the animal system that we use in the lab. This video shows in-vitro transcribed gurken RNA localising to the dorsal-anterior corner of a stage 8 Drosophila egg chamber after injection.

Fly neuromuscular junction - 3D rotation

This is a 3-dimensional image of a Drosophila larva, showing the muscle wall and its associated neurons. The red part of the image is a neuron while the blue circular structures are muscle cell nuclei.
