WebJun 15, 2012 · We discovered that Orc1 could be selectively eluted from chromatin as hamster cells entered S-phase (6) , and a similar observation was reported for human cells (7). Furthermore, we observed that some of the CgOrc1 that was released from chromatin during S-phase was mono-ubiquitinated. WebJul 9, 2010 · In human cells, Orc2–5 forms the core ORC, and Orc1 is transiently associated with this complex (4–7). During the G1 to S phase transition, human Orc1 dissociates from chromatin, is ubiquitylated and degraded by ubiquitin-mediated proteolysis, and is reloaded to the chromatin at the M-G1 transition when new pre-RCs are formed (5, 7–9).
