    摘要: Methods of identifying agents which alter the NAD-dependent acetylation status and mono-ADP-ribosylation of nuclear proteins are disclosed. The methods further include identifying agents which alter the life span or aging of a cell or an organism by determining the level of NAD-dependent acetylation and/or ADP ribosylation of a nuclear protein. The invention also relates to a mammalian Sir2 protein which acetylates or deacetylates nuclear proteins in a NAD-dependent manner and has mono-ADP-ribosyltransferase activity. Host cells producing the Sir2 protein and antibodies to the Sir2 protein are also provided.

    摘要: It has been discovered that Sirt4 possesses an ADP-ribosyltransferase activity. Sirt4 is localized to mitochondria, where it binds to and regulates the activity of proteins such as glutamate dehydrogenase. The ADP-ribosyltransferase activity of Sirt4 is important for the regulation of biological functions such as insulin secretion. Methods of screening for compounds that modulate the expression or activity of Sirt4 are provided. Also provided are methods of modulating insulin secretion, treating metabolic disorders, and treating neurodegenerative disorders by modulating the expression or activity of Sirt4.

    摘要: This invention relates to methods of screening compounds that modulate cellular and organismal processes by modification of the activity of SIR2 and/or transcription factors, e.g., p53, particularly methods of screening for compounds that modify lifespan and/or metabolism of a cell or an organism by modulation of the activity of SIR2 and/or transcription factors, e.g., p53, and more particularly to methods of screening for compounds that modulate the activity of Sir2 and/or transcription factors, e.g., p53. In particular, the present invention relates to a method for screening a compound, by providing a test mixture comprising a transcription factor, Sir2, and a Sir2 cofactor with the compound, and evaluating an activity of a component of the test mixture in the presence of the compound. The invention further relates to therapeutic uses of said compounds. The invention further relates to a method of modifying the acetylation status of a transcription factor binding site on histone or DNA by raising local concentrations of Sir2.
