a The genes that are listed are (i) metal regulated and (ii) have a consensus sequence or sequence that resembles the consensus binding site for the relevant transcription factor within the promoter region and/or encode for a protein that is involved in metal metabolism. Genes that have been analyzed in such a way to demonstrate a more direct interaction with the factor in question are shown in bold. Examples of experimental evidence that is consistent with a direct interaction include analysis of expression in the presence and absence of the wild-type or constitutive alleles of the relevant factor and/or the use of reporter constructs containing the metal-responsive element(s) of the target gene in question.

b No target gene has been identified for the SRE and SreP transcription factors.

c Genes that are repressed, rather than activated, by the named transcription factor.

d Genes which do not fall into any of the listed categories.
