Protein
Probable secreted beta-glucosidase UTH1
Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c)
Function
Involved in aging, oxidative stress response, and in the regulation of mitochondrial biogenesis. Inactivation of UTH1 increases life span, leads to higher resistance to heat stress and against hydrogen peroxide, and increases sensitivity to the superoxide radical-generating drug paraquat and to copper. Also required for the selective autophagic degradation of mitochondria (mitophagy) in response to nitrogen starvation. Involved in the remodeling of the cell wall during the various phases of yeast culture development and under various environmental conditions and plays a role in septation. Involved in cell sensitivity to boric acid.
Similarity
Belongs to the SUN family.
