Webbdb2.ucsd.edu 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).
WebThe ORC1 cycle ensures the dynamic assembly of ORC and MCM on chromatin in G 1 phase, which may correspond to the formation of the pre-RC in human cells, as demonstrated in an accompanying paper ( 24 ).

In addition, we introduced a second mutation in ORC2 in the ORC5 mutant cells, rendering both ORC5 and ORC2 proteins undetectable in the same cells and destabilizing the ORC1, ORC3, and ORC4 proteins.
WebH4K20me2 is enriched at replication origins, and abrogating ORC1 recognition of H4K20me2 in cells impairs ORC1 occupancy at replication origins, ORC chromatin loading and cell-cycle progression.
