Su(var)3-7 | Suppressor of variegation 3-7 (Su(var)3-7) encodes a protein associated with heterochromatin. Increasing the amount of the product of Su(var)3-7 triggers heterochromatin expansion and epigenetic gene silencing. (1250 aa) | ||||
MTF-1 | Metal response element-binding Transcription Factor-1 (MTF-1) encodes a zinc finger protein that primarily controls the homeostasis of physiological trace metals, such as zinc and copper, and the detoxification of non-essential, toxic heavy metals, such as cadmium, mercury, and silver. It activates a number of genes in response to heavy metal load but also induces transcription of the copper importer encoded by Ctr1B upon copper depletion. Variations in the DNA binding site can affect its response to a specific metal. (1006 aa) |
