Day 208 of #LMB365 shows a collage of yeast cells expressing a fluorescently tagged protein which is usually located in the endoplasmic reticulum. Liz Miller’s group deletes individual genes from the yeast genome to see how the fluorescently tagged protein is affected. Each individual image shows cells where a different gene has been deleted. Some of these deletions affect the localisation of the fluorescent protein, indicating a relationship between the two.
