Zap1 transcription factor controls the expression of genes that regulate zinc homeostasis in Saccharomyces cerevisiae. Zap1 contains seven classical C2H2 zinc fingers. This domain corresponds to zinc finger 1 (zf1) which together with zinc finger 2 (zf2) has been shown to be a responsive transcriptional activator. Both zinc fingers interact cooperatively to stabilize the Zn-binding [1].	Domain
A	PF18217	Zap1 zinc finger 2 (Zap1_zf2)	Zap1 zinc finger 2	This domain can be found in Zap1 present in Saccharomyces cerevisiae. Zap1 regulates S. cerevisiae which mediates the transcription of genes encoding uptake vacuolar transporters. This domain corresponds to zinc finger 2 (zf2) which has been shown to ...	This domain can be found in Zap1 present in Saccharomyces cerevisiae. Zap1 regulates S. cerevisiae which mediates the transcription of genes encoding uptake vacuolar transporters. This domain corresponds to zinc finger 2 (zf2) which has been shown to be a constitutive transcriptional activator. The two zinc fingers interactions stabilizes Zn(II)-binding [1].	Domain
