14-3-3sigma is a cruciform DNA binding protein and associates in vivo with origins of DNA replication

A human cruciform binding protein (CBP) was previously shown to bind to cruciform DNA in a structure-specific manner and be a member of the 14-3-3 protein family. CBP had been found to contain the 14-3-3 isoforms beta, gamma, epsilon, and zeta. Here, we show by Western blot analysis that the CBP-cru...
