Predicted to enable transcription cis-regulatory region binding activity. Predicted to be involved in regulation of transcription by RNA polymerase II. Predicted to act upstream of or within several processes, including establishment of Sertoli cell barrier; peptidyl-lysine trimethylation; and regulation of gene expression. Predicted to be located in cytosol; mitochondrion; and nucleoplasm. Predicted to be active in nucleus. Orthologous to human ARID4B (AT-rich interaction domain 4B).
