Summary: Enables histone deacetylase binding activity and protein-macromolecule adaptor activity. Involved in positive regulation of apoptotic process. Acts upstream of or within negative regulation of transcription by RNA polymerase II; oogenesis; and regulation of steroid biosynthetic process. Part of RNA polymerase II transcription repressor complex. Is expressed in several structures, including brain; branchial arch; genitourinary system; hemolymphoid system; and liver. Orthologous to human DDX20 (DEAD-box helicase 20). [provided by Alliance of Genome Resources, Dec 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.
