General description

SIRT1 (sirtuin 1) belongs to the silent information regulator (SIR) 2 family and is a class to HDAC (histone deacetylase). It is expressed in various tissues including brain, liver, pancreas, adipose tissue, and skeletal muscle. SIRT1 is also known as the longevity gene.
Sirtuin-1 (SIRT1) resides in the nucleus.

Immunogen

synthetic peptide corresponding to amino acids 723-736 of human SIRT1, conjugated to KLH via an N-terminal cysteine residue.

Application

Anti-Sirt1 (C-terminal) antibody has been used in
  • immunoblotting
  • immunoprecipitation
  • immunofluorescence
  • immunohistochemistry
  • western blotting

Biochem/physiol Actions

SIRT1 (sirtuin 1) functions as a regulator of various metabolic pathways, and influences the pathophysiology of several metabolic diseases. It is a regulator of protein deacetylation, and is a candidate therapeutic target in non-alcoholic fatty liver disease (NAFLD), amyotrophic lateral sclerosis (ALS), kidney disease, and pulmonary disease. It also participates in tumorigenesis, and whether it functions as an oncogene or as a tumor suppressor depends upon the tumor type. In ancreatic ductal adenocarcinoma (PDAC) its elevated expression is linked with poor prognosis, and innon-small-cell lung cancer (NSCLC) it suppresses the expression of tumor suppressor p27. It is also thought to function as a suppressor of cardiovascular disorders, such as myocardial infarction, or neurodegenerative diseases, such as Alzheimer′s disease (AD) or Parkinson′s disorder (PD).
Sirtuin-1 (SIRT1) is a NAD-dependent deacetylase which has been implicated in the regulation of several transcription factors, including p53, forkhead box protein O (FOXO), nuclear factor kappa-B (NFκB), myocyte-specific enhancer factor 2 (Mef2), and peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1α).
