Abstract

Zinc is an essential micronutrient for all living cells. It serves as a structural and catalytic cofactor for numerous proteins, hence maintaining a proper level of cellular zinc is essential for normal functioning of the cell. Zinc homeostasis is sustained through various ways under severe zinc-deficient conditions. Zinc-dependent proteins play an important role in biological systems and limitation of zinc causes a drastic change in their expression. In budding yeast, a zinc-responsive transcription factor Zap1p controls the expression of genes required for uptake and mobilization of zinc under zinc-limiting conditions. It also regulates the polar lipid levels under zinc-limiting conditions to maintain membrane integrity. Deletion of ZAP1 causes an increase in triacylglyerol levels which is due to the increased biosynthesis of acetate that serves as a precursor for triacylglycerol biosynthesis. In this review, we expanded our recent work role of Zap1p in nonpolar lipid metabolism of budding yeast.
