Web21 de ene. de 2024 · Biotinylated proteins were enriched using Neutravidin agarose. Proteins were resolved by SDS-PAGE and were detected by Western blot using antibodies against GFP, Myc, PARP-13, and actin. Representative figure of data collected over three biological replicates. (b) PARP-7 MARylates PARP-13.2 in cells. WebSpecifically, we found that PARP-7 MARylates α-tubulin to promote microtubule instability, which may regulate ovarian cancer cell growth and motility. In sum, we identified an extensive PARP-7 ADP-ribosylated proteome with important roles in cancer-related cellular phenotypes. KW - ADP-ribosylation. KW - Alpha-tubulin. KW - Chemical biology Web29 de jul. de 2024 · The ADP-ribosyltransferase superfamily. ADP-ribosylation, an ancient modification of proteins, nucleic acids, and metabolites, describes the reversible transfer of ADP-ribose (ADPr) from β-nicotinamide adenine dinucleotide (NAD +) onto a substrate.This modification is central to many cellular processes across all domains of life. radisson blu plaza ljubljana
