Sirt3 - sirtuin 3

Enables NAD-dependent histone deacetylase activity (H3-K14 specific) and sequence-specific DNA binding activity. Involved in peptidyl-lysine deacetylation; positive regulation of ceramide biosynthetic process; and positive regulation of mitochondrial transcription. Acts upstream of or within negative regulation of peptidyl-lysine acetylation and protein deacetylation. Located in mitochondrial inner membrane and mitochondrial matrix. Part of protein-containing complex. Is expressed in several structures, including brain; branchial arch; endocrine gland; genitourinary system; and liver and biliary system. Used to study abdominal obesity-metabolic syndrome. Orthologous to human SIRT3 (sirtuin 3). [provided by Alliance of Genome Resources, Apr 2022]
