    Summary
    Enables RNA polymerase II cis-regulatory region sequence-specific DNA binding activity and chromatin binding activity. Involved in positive regulation of transcription by RNA polymerase II. Acts upstream of or within estrogen receptor signaling pathway; hormone metabolic process; and regulation of growth. Predicted to be located in midbody and nucleoplasm. Predicted to be active in nucleus. Is expressed in several structures, including central nervous system; future brain; olfactory epithelium; reproductive system; and retina layer. Orthologous to human SAFB (scaffold attachment factor B). [provided by Alliance of Genome Resources, Nov 2024]

    RefSeqs maintained independently of Annotated Genomes

    These reference sequences exist independently of genome builds. Explain

    These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
