Summary: Enables NAD-dependent protein lysine deacetylase activity; histone deacetylase activity; and tubulin deacetylase activity. Involved in several processes, including positive regulation of cell cycle process; regulation of gene expression; and regulation of protein metabolic process. Acts upstream of or within several processes, including negative regulation of NLRP3 inflammasome complex assembly; regulation of fat cell differentiation; and tubulin deacetylation. Located in several cellular components, including Schmidt-Lanterman incisure; paranodal junction; and perikaryon. Is expressed in several structures, including brain; liver; oocyte; sensory organ; and spinal cord. Orthologous to human SIRT2 (sirtuin 2). [provided by Alliance of Genome Resources, Nov 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.

See identical proteins and their annotated locations for NP_001116237.1

Status: VALIDATED

Description

Transcript Variant: This variant (2) lacks an alternate in-frame exon in the 5' coding region and uses a downstream start codon, compared to variant 1. The resulting protein (isoform 2) is 37 aa shorter at the N-terminus, compared to isoform 1.
