Sirtuin 1 (SIRT1) tagged posts

Highlights •SIRT1-ΔE2 is a tissue-restricted splice variant of SIRT1 •SIRT1-FL/SIRT1-ΔE2 are indistinguishable vis-à-vis intrinsic catalytic activities •The conserved exon 2 (E2) domain may act to tether substrates •E2 encodes molecular specificity of interactions and functions

Two alternate forms of SIRT1 leads to the discovery of how molecular specificity is encoded. While the search for elixir of life has captivated human imagination for millennia, researchers around the world have put in efforts to extend healthy lifespan and reduce the burden of morbid diseases in an increasingly aging population...
