Transcriptional activator involved in adaptation to weak acid stress; activates transcription of TPO2, YRO2, and other genes encoding membrane stress proteins; HAA1 has a paralog, CUP2, that arose from the whole genome duplication; relocalizes from cytoplasm to nucleus upon DNA replication stress [Source:SGD;Acc:S000006212]
Chromosome XVI: 573,018-575,102 forward strand.
R64-1-1:BK006949.2
This gene has 1 transcript (splice variant), 19 orthologues and 1 paralogue.
