Activates CPS1 and contributes to the regulation of blood ammonia levels during prolonged fasting: acts by mediating desuccinylation and deglutarylation of CPS1, thereby increasing CPS1 activity in response to elevated NAD levels during fasting (PubMed:22076378, PubMed:24703693). Activates SOD1 by mediating its desuccinylation, leading to reduced reactive oxygen species (PubMed:24140062). Modulates ketogenesis through the desuccinylation and activation of HMGCS2 (By similarity). Has weak NAD-dependent protein deacetylase activity; however this activity may not be physiologically relevant in vivo. Can deacetylate cytochrome c (CYCS) and a number of other proteins in vitro such as UOX. {ECO:0000250|UniProtKB:Q8K2C6, ECO:0000269|PubMed:18680753, ECO:0000269|PubMed:21908771, ECO:0000269|PubMed:22076378, ECO:0000269|PubMed:24140062, ECO:0000269|PubMed:24703693}. |SIR2| |protein-glutaryllysine deglutarylase activity| |protein deglutarylation| |protein-malonyllysine demalonylase activity| |peptidyl-lysine deglutarylation| |peptidyl-lysine desuccinylation| |peptidyl-lysine demalonylation| |protein desuccinylation| |protein demalonylation| |protein-succinyllysine desuccinylase activity| |NAD-dependent protein deacetylase activity| |regulation of ketone biosynthetic process| |NAD+ binding| |negative regulation of cardiac muscle cell apoptotic process| |negative regulation of striated muscle cell apoptotic process| |NAD+ ADP-ribosyltransferase activity| |protein ADP-ribosylation| |regulation of cardiac muscle cell apoptotic process| |negative regulation of muscle cell apoptotic process| |regulation of striated muscle cell apoptotic process| |protein deacetylation| |negative regulation of reactive oxygen species metabolic process| |chromatin organization involved in negative regulation of transcription| |chromatin silencing| |protein deacylation| |macromolecule deacylation| |regulation of muscle cell apoptotic process| |chromatin organization involved in regulation of transcription| |mitochondrial intermembrane space| |negative regulation of gene expression, epigenetic| |gene silencing| |regulation of cellular ketone metabolic process| |regulation of reactive oxygen species metabolic process| |regulation of gene expression, epigenetic| |peptidyl-lysine modification| |mitochondrial matrix| |mitochondrial inner membrane| |regulation of small molecule metabolic process| |mitochondrion organization| |response to nutrient levels| |response to extracellular stimulus| |chromatin organization| |zinc ion binding| |peptidyl-amino acid modification| |negative regulation of apoptotic process| |negative regulation of programmed cell death| |negative regulation of cell death| |chromosome organization| |negative regulation of transcription, DNA-templated| |negative regulation of nucleic acid-templated transcription| |negative regulation of RNA biosynthetic process| |mitochondrion| |negative regulation of RNA metabolic process| |negative regulation of cellular macromolecule biosynthetic process| |negative regulation of nucleobase-containing compound metabolic process| |negative regulation of macromolecule biosynthetic process| |negative regulation of cellular biosynthetic process| |regulation of apoptotic process| |negative regulation of biosynthetic process| |regulation of programmed cell death| |regulation of cell death| |negative regulation of gene expression| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp508|NN-Dimethylsphingosine 2.5μM R08 exp508]]|-2.11| |[[:results:exp401|SNS-032 25μM R07 exp401]]|1.83| No correlation found to any other genes in chemogenomics.
