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. irish catholic records online

WebBinding of ORC to replication origins is a key step in initiation of DNA replication, leading to the recruitment of other prerep- lication complex (pre-RC) proteins including Cdc6, Cdt1, and the MCM2-7.
