Structure of PCNA from Drosophila melanogaster

Proliferating cell nuclear antigen (PCNA) plays essential roles in DNA replication, DNA repair, cell-cycle regulation and chromatin metabolism. The PCNA from Drosophila melanogaster (DmPCNA) has been purified and crystallized.

Structure of zebrafish MO25

The conserved protein MO25 activates STE20 family kinases. The crystal structure of zebrafish MO25 is reported, which is similar to that of human MO25.
