WebCuriously, MCM3AP inhibits DNA replication in a cell-free system, suggesting that it is a negative regulator (307, 308); however, it clearly functions positively by promoting Mcm3 nuclear localization and chromatin binding (307, 309). This paradox has yet to be resolved. Webgether these results suggest that inhibition of SV40 origin-based DNA replication by the CMV enhancer is due to intramolecular competition for the formation of active chromatin …
