    Summary
    Enables transcription coactivator activity. Involved in positive regulation of miRNA transcription; positive regulation of striated muscle tissue development; and positive regulation of transcription by RNA polymerase II. Predicted to be located in cytoplasm. Predicted to be active in several cellular components, including glutamatergic synapse; postsynapse; and presynapse.

    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.
