Gene: SNORA56

Alternate names for this Gene: ACA56

Gene Summary: Biosynthesis of stable cellular RNAs such as tRNAs, rRNAs, snRNAs, and snoRNAs is aided by covalent nucleotide modification after transcription. The modified nucleotides are involved in correct RNA folding, establishment of correct RNA-RNA and RNA-protein interactions, and in the correct function of mature RNAs. The RNA encoded by this gene is thought to mediate the pseudouridylation of residue U1664 of 28S rRNA.

Gene is located in Chromosome: X

Location in Chromosome : Xq28

Description of this Gene: small nucleolar RNA, H/ACA box 56

Type of Gene: snoRNA

Gene: DKC1

Alternate names for this Gene: CBF5|DKC|DKCX|NAP57|NOLA4|XAP101

Gene Summary: This gene functions in two distinct complexes. It plays an active role in telomerase stabilization and maintenance, as well as recognition of snoRNAs containing H/ACA sequences which provides stability during biogenesis and assembly into H/ACA small nucleolar RNA ribonucleoproteins (snoRNPs). This gene is highly conserved and widely expressed, and may play additional roles in nucleo-cytoplasmic shuttling, DNA damage response, and cell adhesion. Mutations have been associated with X-linked dyskeratosis congenita. Alternative splicing results in multiple transcript variants.
