Hsf1 Gene Summary [Rat]
Enables several functions, including STAT family protein binding activity; promoter-specific chromatin binding activity; and sequence-specific single stranded DNA binding activity. Involved in several processes, including regulation of apoptotic process; regulation of inclusion body assembly; and regulation of macromolecule metabolic process. Located in euchromatin and heterochromatin. Used to study Parkinson's disease; muscular atrophy; and transient cerebral ischemia. Biomarker of Alzheimer's disease; Parkinson's disease; congestive heart failure; cryptorchidism; and transient cerebral ischemia. Human ortholog(s) of this gene implicated in Huntington's disease. Orthologous to human HSF1 (heat shock transcription factor 1). [provided by Alliance of Genome Resources, Jul 2025]
