Summary: This gene encodes a member of the sirtuin family of proteins, homologs to the yeast Sir2 protein. Members of the sirtuin family are characterized by a sirtuin core domain and grouped into four classes. The functions of human sirtuins have not yet been determined; however, yeast sirtuin proteins are known to regulate epigenetic gene silencing and suppress recombination of rDNA. Studies suggest that the human sirtuins may function as intracellular regulatory proteins with mono-ADP-ribosyltransferase activity. The protein encoded by this gene is included in class I of the sirtuin family. Several transcript variants are resulted from alternative splicing of this gene. [provided by RefSeq, Jul 2010]

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.

See identical proteins and their annotated locations for NP_001180215.1

Status: REVIEWED

Description

Transcript Variant: This variant (3) lacks an exon in the 5' region, resulting in a downstream in-frame AUG start codon, and also lacks a big segment in the 3' region, resulting in a frame-shift, as compared to variant 1. The resulting isoform (3) has a shorter N-terminus, and a shorter and different C-terminus, as compared to isoform 1.

NR_034146.1 RNA Sequence

Status: REVIEWED

Description

Transcript Variant: This variant (4) lacks the 5' two exons but has an alternate 5' segment, resulting in an upstream open reading frame (uORF) with strong Kozak signal, as compared to variant 1. The uORF overlaps the downstream ORF (dORF), and inhibits the protein translation from the dORF. Therefore, this transcript is a nonsense-mediated mRNA decay candidate and can not make a functional protein.
