basic FUNCTION
| acting as a NAD-dependent deacetylase |
|
activating mitochondria functions and playing an important role in adaptive thermogenesis in brown adipose |
|
may play a role in life span |
|
important for regulation of mitochondrial metabolism, cell survival, and longevity |
|
major mitochondrial deacetylase, having evolved to control reversible lysine acetylation in the mitochondria |
|
can deacetylate and thereby activate a central metabolic regulator in the mitochondrial matrix, glutamate dehydrogenase |
|
essential role of SIRT3 in the survival of cardiomyocytes in stress situations |
|
might function in nucleus |
|
by participating in the stress response to genomic insults, sirtuins are thought to protect against cancer, but they are also emerging as direct participants in the growth of some cancers |
|
NAD(+)-dependent protein deacetylases that regulate cellular functions through deacetylation of a wide range of protein targets |
|
required to maintain cell survival after genotoxic stress in a NAD+-dependent manner |
|
with SIRT4, modulate mitochondrial function in response to its [NADH]/[NAD+] ratio by regulating the activity of key metabolic enzymes |
|
stimulates deacetylation of MRPL10, consequently regulating protein synthesis in mammalian mitochondria |
|
mitochondria-localized tumor suppressor required for maintenance of mitochondrial integrity and metabolism during stress |
|
essential player in enhancing the mitochondrial glutathione antioxidant defense system during caloric restriction suggesting that SIRT3-dependent mitochondrial adaptations may be a central mechanism of aging retardation, and age-related hearing loss |
|
during caloric restriction, promotes a more reductive environment in mitochondria of multiple tissues, thereby enhancing the glutathione antioxidant defense system |
|
mediates reduction of oxidative stress by stimulating IDH2 activity and increasing NADPH levels under stress conditions |
|
integral regulator of mitochondrial function and its depletion results in hyperacetylation of critical mitochondrial proteins that protect against hepatic lipotoxicity under conditions of nutrient excess |
|
acts as a tumor suppressor via its ability to suppress reactive oxygen species (ROS) and regulate hypoxia inducible factor 1A (HIF1A) |
|
acts to suppress the growth of tumors, at least in part through its ability to suppress ROS and HIF1A |
|
SIRT3-dependent deacetylation exacerbates acetaminophen hepatotoxicity |
|
plays an important role in diabetes through regulation of mitochondrial oxidation, reactive oxygen species production, and insulin resistance in skeletal muscle |
|
link between SIRT3, mitochondrial DNA variability and mitochondrial functionality, three fundamental components of the cellular stress response |
|
SIRT3-mediated deacetylation has recently emerged as a major mechanism regulating the activity of mitochondrial oxidative and intermediary metabolism |
|
key role for SIRT3 in the maintenance of oxidative metabolism that may be especially important in the heart |
|
SIRT3 is a potential regulator of IDH2-dependent functions in cancer cell metabolism |
|
can protect cells from mitochondrial oxidative stress and this effect is almost entirely dependent on IDH2 |
|
key factor in a coordinate up-regulation of oxidative metabolism and antioxidant pathways in response to acute and chronic caloric restriction |
|
exhibits a previously unappreciated role in the nucleus, modulating the expression of some stress-related and nuclear-encoded mitochondrial genes |
|
plays an important role in skeletal muscle mitochondrial substrate choice and metabolic flexibility in part by regulating PDH function through deacetylation |
|
role for SIRT3 in the suppression of epidermal differentiation via lowering oxidative stress |
|
novel function of SIRT3 which was found to be involved in mitosis |
|
is not a tubulin deacetylase but regulates the attachment of spindle microtubules to the kinetochore and the subsequent chromosome alignment by increasing spindle dynamics |
|
major mitochondria NAD+-dependent deacetylase, may target mitochondrial proteins for lysine deacetylation and also regulate cellular functions |
|
acts as a prosurvival factor playing an essential role to protect cortical neurons under H2O2 induced oxidative stress, possibly through regulating mitochondrial Ca2+ homeostasis and mitochondrial biogenesis |
|
role in keratinocyte differentiation, wound healing, chronological aging, ultraviolet radiation (UVR) and ozone response, systemic sclerosis, melanoma, basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) |
