Ribosome adp-ribosylation
Webb14 feb. 2024 · ADP-ribosylation is a PTM, in which ADP-ribosyltransferases use nicotinamide adenine dinucleotide (NAD +) to modify target proteins with ADP-ribose. This modification can occur as mono- or poly-ADP-ribosylation. The latter involves the … 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 …
