Recombinant Human SIRT2

Background

SIRT2 is another NAD+-dependent deacetylase that primarily localizes in the cytoplasm but can translocate to the nucleus under certain conditions to regulate cell cycle progression, metabolism, and oxidative stress SIRT2 deacetylates proteins involved in microtubule dynamics, such as α-tubulin, to maintain cellular morphology and mitotic integrity It also targets transcription factors including FOXO and p53, regulating cell proliferation, apoptosis, and stress resistance SIRT2 has a dual role in tumorigenesis, acting as a tumor suppressor by inhibiting cell proliferation and as a tumor promoter depending on the cellular context SIRT2 plays an essential role in metabolic regulation, particularly during caloric restriction, by modulating gluconeogenesis, insulin sensitivity, and lipid metabolism Dysregulation of SIRT2 has been linked to neurodegenerative diseases, including Parkinson’s disease and Alzheimer’s disease, where it influences protein aggregation and neuronal survival Pharmacological modulation of SIRT2 is under investigation for its therapeutic potential in cancer, metabolic disorders, and neurodegeneration
