The PRC2 complexes contain histone deacetylases that inhibit transcription. They also contain a subunit [E(z) in Drosophila, EZH2 in mammals] with a SET domain, which is the catalytic domain of several histone methyl transferases.

Profilin enhances the exchange of ADP for ATP on G-actin. Cofilin enhances the rate of loss of ADP-actin from the filament (−) end. Thymosin-β4, binds to ATP–G-actin in such a way that it inhibits addition of the actin subunit to either end of the filament.

In one minute, each NPC is estimated to import 60,000 protein molecules into the nucleus, while exporting 50–250 mRNA molecules, 10–20 ribosomal subunits, & 1000 tRNAs out of the nucleus.
