Predicted to enable several functions, including DNA-binding transcription factor activity, RNA polymerase II-specific; HMG box domain binding activity; and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Involved in negative regulation of transcription by RNA polymerase II. Predicted to be located in cytosol and nucleoplasm. Predicted to be active in nucleus. Human ortholog(s) of this gene implicated in agnathia-otocephaly complex. Orthologous to human PRRX1 (paired related homeobox 1). [provided by Alliance of Genome Resources, Apr 2022]
