Functional Description ? help Back to Top
Source	Description
UniProt	Transcriptional activator that specifically binds DNA sequence 5'-AGAAnnTTCT-3' known as heat shock promoter elements (HSE). Involved in heat stress responses. Seems to be involved in other environmental stress responses. Activates ascorbate peroxidase 2 (APX2) in addition to several heat shock protein (HSPs). {ECO:0000269\|PubMed:16649111, ECO:0000269\|PubMed:17059409, ECO:0000269\|PubMed:17085506}.
