Protein

Anion/proton exchange transporter GEF1

Gene

GEF1

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Anion/proton exchange transporter involved in iron and copper cation homeostasis. Involved in intracellular iron metabolism during growth on fermentable and non fermentable carbon sources. Required for proper copper-loading and maturation of multicopper oxidase FET3. Important for adjusting intracellular compartment pH to more alkaline pH under iron limitation. May also transport chloride ions through the plasma membrane.5 Publications
