Summary: Enables single-stranded RNA binding activity and ubiquitin-protein transferase activator activity. Predicted to be involved in positive regulation of cell population proliferation; positive regulation of collagen biosynthetic process; and regulation of nucleobase-containing compound metabolic process. Predicted to act upstream of or within heterochromatin formation. Located in heterochromatin and nucleus. Part of PRC1 complex. Is expressed in several structures, including brain. Orthologous to human CBX8 (chromobox 8). [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.
