Webb16 dec. 2024 · Although PARP9 has no ADP-ribosylation activity, it interacts with signal transducer and activator of transcription 1 (STAT1) through its macro domains in an ADP-ribosylation–dependent manner. As a consequence, PARP9 mediates proliferation, survival, and chemoresistance in DLBCL by repressing the anti-proliferative and pro …
Ribosome adp-ribosylation
Did you know?
ADP-ribosylation is the addition of one or more ADP-ribose moieties to a protein. It is a reversible post-translational modification that is involved in many cellular processes, including cell signaling, DNA repair, gene regulation and apoptosis. Improper ADP-ribosylation has been implicated in some forms of cancer. It is also the basis for the toxicity of bacterial compounds such as cholera toxin, dip… Webb26 juli 2024 · Ribosome ADP-ribosylation inhibits translation and maintains proteostasis in cancers Highlights • The cytosolic NAD + synthase NMNAT-2 is highly upregulated in ovarian cancers • Ribosome MARylation requires NAD + from NMNAT-2, as well as the …
Webb14 feb. 2024 · ADP-ribosylation is a PTM, in which ADP-ribosyltransferases use nicotinamide adenine dinucleotide (NAD +) to modify target proteins with ADP-ribose.
