Predicted to enable DNA-binding transcription repressor activity, RNA polymerase II-specific; RNA polymerase II cis-regulatory region sequence-specific DNA binding activity; and protein dimerization activity. Predicted to be involved in negative regulation of transcription by RNA polymerase II and positive regulation of transcription by RNA polymerase II. Predicted to act upstream of or within nucleocytoplasmic transport. Predicted to be located in cytosol; nuclear membrane; and nucleoplasm. Predicted to be active in nucleus. Orthologous to human MLX (MAX dimerization protein MLX). [provided by Alliance of Genome Resources, Apr 2022]
