Description

Description générale

NAD-dependent protein deacetylase sirtuin-1 (UniProt Q923E4; also known as Sir2, mSIRT2a, NAD-dependent deacetylase sirtuin-1, Regulatory protein SIR2 homolog 1, Sir2-like 1, SIR2-like protein 1, SIR2alpha) is encoded by the Sirt1 (also known as Sir2l1) gene (Gene ID 93759) in murine species. Sirtuins constitute a family of NAD+-dependent deacetylases found in nearly all organisms. Sirtuins have been implicated in the regulation of aging, transcription, apoptosis, and stress resistance. Full-length SirT1 (FLSirT1) plays an important role in human cartilage homeostasis and chondrocyte survival by mediating the expression of major cartilage anabolic components, collagen 2(I) & aggrecan. The generation of the transcriptionally inactive 75-kDa fragment (75SirT1) via site-specific cleavage of FLSirT1 at amino acid 533 by cathepsin B is an anti-apoptotic mechanism to promote human osteoarthritic (OA) chondrocytes survival following exposure to proinflammatory cytokines. The 5SirT1 fragment is shown to associate with cytochrome c and likely blocks downstream apoptosome assembly. Phosphorylation plays an important role in modulating SirT1 activity and cellular functions. Multiple kinases and their corresponding SirT1 phosphorylation sites have been identified, including pT344 targeted by AMPK, pT530 and pS540 targeted by Cdk1/Cyclin B, pS46 (mouse) or pS47 (human) targeted by JNK1, pT522 targeted by DYRK1A & DYRK3, as well as pS27 & pS47 targeted by CaMKKβ.
