Predicted to enable RNA polymerase II transcription regulatory region sequence-specific DNA binding activity; chromatin binding activity; and histone binding activity. Predicted to be involved in several processes, including immune system development; negative thymic T cell selection; and regulation of thymocyte migration. Predicted to be located in cytoplasm. Predicted to be active in nucleus. Human ortholog(s) of this gene implicated in autoimmune polyendocrine syndrome and autoimmune polyendocrine syndrome type 1. Orthologous to human AIRE (autoimmune regulator).
