Heat shock factor protein 2

Gene

Hsf2

Organism
Mus musculus (Mouse)
Status
Reviewed-Annotation score: -Experimental evidence at transcript leveli

Functioni

DNA-binding protein that specifically binds heat shock promoter elements (HSE) and activates transcription. In higher eukaryotes, HSF is unable to bind to the HSE unless the cells are heat shocked. HSF2 is expressed in a form that binds DNA constitutively but loses DNA binding by incubation at greater than 41 degrees C.

Expressioni

Tissue specificityi

Isoform alpha is expressed predominantly in testis while isoform beta is expressed predominantly in heart and brain.1 Publication

Developmental stagei

In the 7-day-old testis, isoform beta is expressed at significantly higher levels than isoform alpha. As development proceeds, the levels of isoform alpha gradually increase so that it is the predominant isoform in mature testes.1 Publication
