Heat shock transcription factor 2 (HSF2)

Heat shock transcription factor 2 is a DNA-binding transcription factor that activates gene expression in response to various stresses—most notably proteotoxic and heat stress—by binding to specific DNA sequences known as heat shock promoter elements (HSE)[1][2][4]. HSF2 is part of the heat shock factor family in humans, along with HSF1 and HSF4, and plays essential roles in cellular adaptation to stress, development, and disease. In higher eukaryotes, HSF2 remains largely inactive under normal conditions and is activated primarily during stress or specific developmental contexts[1][2][3][4]. It regulates genes involved in protein folding, quality control, and cell protection; aberrant HSF2 function has been implicated in diseases such as cancer, neurodegenerative disorders, and certain forms of infertility and red blood cell cancers[2][3]. Unlike HSF1, direct pharmacological targeting of HSF2 is not well established, but its critical regulatory roles and disease associations make it a growing area of interest for therapeutic development.
