CDT1 Lysates

Geminin is a protein that inhibits DNA replication by preventing the loading of MCM complex on chromatin. Human CDT1 is a 65kDa protein that contains 546 amino acids and coimmunoprecipitates with Geminin. Inhibition of DNA replication by Geminin in cell-free cDNA replication extracts can be reversed by the addition of excess CDT1. In the normal cell cycle, CDT1 is present only in G1 and S phases, whereas Geminin is present in S and G2 phases. Wohlschlegel et al. (2000) concluded that their ...
