Summary
Predicted to enable several functions, including enzyme binding activity; protein C-terminus binding activity; and protein heterodimerization activity. Acts upstream of or within axonogenesis; forebrain development; and neuron migration. Located in nucleus. Is expressed in central nervous system; genitourinary system; and retina. Orthologous to human TOP2B (DNA topoisomerase II beta). [provided by Alliance of Genome Resources, Nov 2021]

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.
