Abstract
It is becoming increasingly apparent that stress signalling is important for tolerance of fungal species to antifungal chemicals and proteins. The high-osmolarity glycerol (HOG) pathway responds to a number of stressors including osmotic and oxidative stress. This protocol describes a method to detect activation of the Candida albicans (C. albicans) MAPK Hog1 by monitoring its phosphorylation in response to an antifungal protein.
