Predicted to enable several functions, including DNA-binding transcription repressor activity, RNA polymerase II-specific; NFAT protein binding activity; and enzyme binding activity. Involved in several processes, including establishment of endothelial blood-brain barrier; negative regulation of defense response to virus; and response to rapamycin. Predicted to be located in cytoplasm and nucleoplasm. Predicted to be active in nucleus. Used to study intrahepatic cholangiocarcinoma. Biomarker of Korean hemorrhagic fever; asthma; bronchiolitis obliterans; hypertension; and hypothyroidism. Human ortholog(s) of this gene implicated in Human papillomavirus infectious disease; colorectal cancer; immune dysregulation-polyendocrinopathy-enteropathy-X-linked syndrome; pulmonary tuberculosis; and type 1 diabetes mellitus. Orthologous to human FOXP3 (forkhead box P3). [provided by Alliance of Genome Resources, Apr 2022]
