Merck, 05-1243, Anti-Sirt1 Antibody, clone 3H10.2

General description
120 kDa
The Sir2 protein in yeast is known to function in transcriptional silencing processes through the deacetylation of histones H3 and H4. The more recently described human homologue of Sir2, known as SIRT1, has been found to associate with the tumor suppressor protein p53. There are now five described human homologs of yeast Sir2, which are named SIRT1-5.
SIRT1 binds and deacetylates p53 with specificity for its C-terminal Lys382 residue in response to the upregulation of promyelocytic leukemia protein (PML) nuclear bodies or oncogenic Ras. The deacetylation of p53 SIRT1 has been shown to negatively regulate p53-mediated transcription, preventing cellular senescence and apoptosis induced by DNA damage and stress. SIRT1 is a HDAC which is important in establishing repressive chromatin structures and plays a role in increasing lifespan.
