SirT1 (Phospho-Ser47) Antibody

Description

Product Name SirT1 (Phospho-Ser47) Antibody
Host Species Rabbit
Clonality Polyclonal
Purification Antibodies were produced by immunizing rabbits with synthetic phosphopeptide and KLH conjugates. Antibodies were purified by affinity-chromatography using epitope-specific phosphopeptide. Non-phospho specific antibodies were removed by chromatogramphy using non-phosphopeptide.
Applications WB
Species Reactivity Hu
Specificity The antibody detects endogenous level of SirT1 only when phosphorylated at serine 47.
Immunogen Type Peptide-KLH
Immunogen Description Peptide sequence around phosphorylation site of serine 47(E-R-S(p)-P-G) derived from Human SirT1.

Background

NAD-dependent protein deacetylase that links transcriptional regulation directly to intracellular energetics and participates in the coordination of several separated cellular functions such as cell cycle, response to DNA damage, metobolism, apoptosis and autophagy. Can modulate chromatin function through deacetylation of histones and can promote alterations in the methylation of histones and DNA, leading to transcriptional repression. Deacetylates a broad range of transcription factors and coregulators, thereby regulating target gene expression positively and negatively.
