Webb24 feb. 2024 · First, replication stalling induces mono-ubiquitination of PCNA, a homo-trimeric substrate for the E2 conjugating enzyme RAD6 and E3 ligase RAD18 [ 6 ]. The mono-ubiquitination of PCNA at lysine 164 site recruits the DNA repair proteins REV1 and Pol η to the DNA damage site [ 7 ]. WebbArginine shortage increases HLTF-mediated PCNA K63-linked polyubiquitination and PCNA occupancy on the stalled nascent DNA strands. Next, we find that under replication stress induced by hydroxyurea (HU), arginine-starved cells exhibit vigorous nascent strand degradation, when HLTF is depleted, in a manner dependent on DNA2. dave harmon plumbing goshen ct
