Unveiling the mechanism protecting replicated DNA from degradation

Researchers have succeeded in depleting AND-1, a key protein for DNA replication, by using a recently developed conditional protein degradation system. Consequently, they were able to gain unprecedented access to the mechanism behind how AND-1 works during DNA replication and cell proliferation in vertebrate cells, demonstrating that AND-1 has two different functions during DNA replication mediated by different domains of AND-1.
