Srebf1 Gene Summary [Rat]
Enables DNA-binding transcription activator activity, RNA polymerase II-specific; RNA polymerase II cis-regulatory region sequence-specific DNA binding activity; and chromatin binding activity. Involved in several processes, including cellular response to insulin stimulus; response to glucagon; and response to progesterone. Part of protein-containing complex. Biomarker of alcoholic hepatitis; diabetic neuropathy; kidney disease; lipid storage disease (multiple); and type 2 diabetes mellitus. Human ortholog(s) of this gene implicated in coronary artery disease; disease of metabolism; and type 2 diabetes mellitus. Orthologous to human SREBF1 (sterol regulatory element binding transcription factor 1). [provided by Alliance of Genome Resources, Jul 2025]
