Summary: Predicted to enable box H/ACA snoRNA binding activity; pseudouridine synthase activity; and telomerase RNA binding activity. Predicted to contribute to telomerase activity. Involved in positive regulation of cell population proliferation and snoRNA guided rRNA pseudouridine synthesis. Located in Cajal body. Part of box H/ACA snoRNP complex. Human ortholog(s) of this gene implicated in X-linked dyskeratosis congenita; aplastic anemia; and dyskeratosis congenita. Orthologous to human DKC1 (dyskerin pseudouridine synthase 1).

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.
