Identification of distinct amino acids as ADP-ribose acceptor sites by mass spectrometry


Rosenthal, F; Messner, S; Roschitzki, B; Gehrig, P; Nanni, P; Hottiger, M O (2011). Identification of distinct amino acids as ADP-ribose acceptor sites by mass spectrometry. Methods in Molecular Biology, 780(Part 1):57-66.

Abstract

ADP-ribosylation is a well-known post-translational protein modification, which regulates a variety of -cellular processes. The proteins able to catalyze mono- or poly ADP-ribosylation of proteins belong to the family of ADP-ribosyltransferases. A variety of nuclear proteins has been described to be ADP-ribosylated, including ARTD1 itself and histone proteins. Despite intensive research during the last 40 years, the acceptor amino acids in ARTD1 or histone proteins could be identified and confirmed only recently by MS/MS and by site-directed mutagenesis. The establishment of a standardized protocol including the specific enrichment of ADP-ribosylated proteins and peptides and subsequent mass spectrometric analysis allows the identification of ADP-ribose acceptor sites of modified proteins and to address the functional contribution of ADP-ribosylation in vitro as well as in vivo.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
