HSF2
gene geneOn this page
Summary
HSF2 (heat shock transcription factor 2, HGNC:5225) is a protein-coding gene on chromosome 6q22.31, encoding Heat shock factor protein 2 (Q03933). DNA-binding protein that specifically binds heat shock promoter elements (HSE) and activates transcription.
The protein encoded by this gene belongs to the HSF family of transcription factors that bind specifically to the heat-shock promoter element and activate transcription. Heat shock transcription factors activate heat-shock response genes under conditions of heat or other stresses. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.

Enriched among interaction partners
Reactome pathways and GO biological processes over-represented among this gene’s 75 IntAct physical interaction partners (hypergeometric vs the genome-wide background, BH-FDR, gene-set size 15–500, ranked by fold). A functional readout of the neighbourhood — distinct from this gene’s own memberships above, and biased toward well-studied / hub proteins, so read it as themes rather than proof.
