A new approach to stabilizing protein structures could be key to an efficient vaccine

Snd2 was tagged with a green fluorescent protein, and the endoplasmic reticulum was marked with a red fluorescent protein. The overlap between the green and red microscopy signals indicates that the newly discovered Snd2 is a receptor on the endoplasmic reticulum membrane.
