Predicted to enable transcription cis-regulatory region binding activity. Acts 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; nucleoplasm; and plasma membrane. Predicted to be part of transcription repressor complex. Predicted to be active in nucleus. Used to study acute myeloid leukemia. Orthologous to human ARID4A (AT-rich interaction domain 4A). [provided by Alliance of Genome Resources, Apr 2022]
