PRC1 complex binds the methylated nucleosomes through dimeric Pc subunits (CBXs in mammals), each containing a methyl lysine–binding domain (called a chromodomain) specific for methylated H3 lysine 27. 

Binding of the dimeric Pc to neighboring nucleosomes is proposed to condense the chromatin into a structure that inhibits transcription.

IEF takes place in a pH gradient and can only be used for amphoteric substances such as peptides and proteins. The charged molecules move toward the anode or the cathode until they reach a position in the pH gradient where their net charges are zero. This pH value is the “isoelectric point” (pI) of the substance.
