Summary

In this interview, Sean Munro, a group leader at the MRC Laboratory of Molecular Biology (LMB), discusses his career and research. He begins by explaining the fundamental question of cell biology: how cells secrete proteins like insulin and antibodies. He describes the secretory pathway, focusing on the Golgi apparatus, which modifies and sorts proteins. Munro explains his long-standing interest in how Golgi enzymes stay in place while cargo passes through, a question that has led to the ‘cisternal maturation’ model. He recounts his education, from an initially boring biochemistry course at Oxford to a PhD at the LMB under Hugh Pelham, where he helped develop epitope tagging. He describes his early career, including starting his own lab at age 27, and the freedom and support he has enjoyed at the LMB. He discusses his work on the Golgi, including switching to yeast genetics and later to Drosophila. He highlights the excitement of using a prototype confocal microscope to visualize the endoplasmic reticulum. Munro also reflects on his role as Head of Division, which involved recruiting new scientists, and his oversight of the light microscopy facility. He concludes by explaining why he has stayed at the LMB for so long, citing the supportive environment and personal reasons.
