Protein: Metal-binding activator 1 (P35192)
Organism: Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Function: Regulatory protein involved in Cu/Fe utilization and stress resistance. Involved in basal level transcription of FRE1 and H(2)O(2)-induced transcription of CTT1. Regulates the transcription of CTR1 and CTR3 via the copper ion responsive elements in their promoters. Required for degradation of CTR1.
Subcellular location: Nucleus.
InterPro domains:
- IPR051763: Copper Homeostasis Regulator (family) [1-302]
- IPR036395: Copper fist DNA-binding domain superfamily (homologous_superfamily) [1-41]
- IPR001083: Copper fist DNA-binding domain (domain) [1-40]
