SIRT2, or sirtuin 2, is one of the members of the sirtuin family of proteins, which are class III histone deacetylases. The sirtuin family consists of seven members, SIRT1 to SIRT7, playing pivotal roles in cellular health, aging, and metabolism. SIRT2 has garnered significant attention due to its distinct cellular locations, versatile functions, and potential implications in various diseases, including neurodegenerative conditions and cancers.
In humans, SIRT2 is predominantly located in the cytoplasm, where it exhibits its deacetylase activity on a multitude of substrates. It’s crucial in maintaining cellular homeostasis, involved in processes such as the cell cycle, energy metabolism, and cellular differentiation. SIRT2’s role in these processes highlights its importance in understanding more about human biology, diseases, and aging.
Studying SIRT2 can provide crucial insights into the development of therapeutic strategies for numerous diseases, as modulation of its activity has demonstrated impactful results in cellular models. The pharmacological targeting of SIRT2 has thus become a focal point in research related to aging and age-related diseases.

SIRT2's multifunctional roles in cell biology are central to maintaining cellular equilibrium and function. It is deeply interwoven in a multitude of cellular processes, ensuring the cell's well-being and its response to the surrounding environment.
Within the cell, SIRT2 primarily functions as a deacetylase, removing acetyl groups from various protein substrates. This deacetylation is pivotal in modulating protein functions and interactions, essentially regulating cellular activities such as the cell cycle, metabolism, and differentiation. The dysregulation of SIRT2 can thus result in a myriad of cellular anomalies and conditions, underscoring its vital role in cell biology.
SIRT2’s role in the cell cycle is particularly noteworthy. It contributes to maintaining the balance between cell proliferation and cell death, ensuring cellular sustainability and preventing anomalous cell growth. SIRT2 has been shown to deacetylate several substrates related to cell cycle progression, consequently affecting the stability and activity of these proteins.
Its influence extends to cellular metabolism as well. SIRT2 modulates metabolic processes, including glycolysis and lipid metabolism, affecting the cell's energy production and utilization.
