Fig. 4From: Independent functions of DNMT1 and USP7 at replication fociUSP7 is recruited to replication foci in the absence of DNMT1. Replication foci where identified by staining for the replication factor PCNA. Colocalization of USP7 and PCNA is clearly apparent in both wild type (top three rows) and Dnmt1-null (bottom three rows) ES cell nucleiBack to article page
