KAT6 histone acetyltransferases (HATs) are highly conserved in eukaryotes and are
involved in cell cycle regulation. However, information regarding their roles in
regulating cell cycle progression is limited. Here, we report the identification
of subunits of the Drosophila Enok complex and demonstrate that all subunits are
important for its HAT activity. We further report a novel interaction between the
Enok complex and the Elg1 proliferating cell nuclear antigen (PCNA)-unloader
complex. Depletion of Enok in S2 cells resulted in a G1/S cell cycle block, and
this block can be partially relieved by depleting Elg1. Furthermore, depletion of
Enok reduced the chromatin-bound levels of PCNA in both S2 cells and early
embryos, suggesting that the Enok complex may interact with the Elg1 complex and
down-regulate its PCNA-unloading function to promote the G1/S transition.
Supporting this hypothesis, depletion of Enok also partially rescued the
endoreplication defects in Elg1-depleted nurse cells. Taken together, our study
provides novel insights into the roles of KAT6 HATs in cell cycle regulation
through modulating PCNA levels on chromatin.
