MIG2/YGL209W Summary Help

Standard Name MIG2 1
Systematic Name YGL209W
Alias MLZ1 2
Feature Type ORF, Verified
Description Zinc finger transcriptional repressor; cooperates with Mig1p in glucose-induced repression of many genes; under low glucose conditions Mig2p relocalizes to mitochondrion, where it interacts with Ups1p and antagonizes mitochondrial fission factor, Dnm1p, indicative of a role in mitochondrial fusion or regulating morphology; regulates filamentous growth along with Mig2p in response to glucose depletion; MIG2 has a paralog, MIG3, that arose from the whole genome duplication (1, 3, 4, 5)
