Cover Story: Intrinsically disordered regions (IDRs) are known to cause the oligomerization and accumulation of many proteins. In addition, plants utilize a novel mechanism harnessing the oligomerization capacity of α-Crystalline Domain (ACD)-containing proteins to accumulate the MBD5/6-silencing complex at DNA methylation sites within nuclear chromocenters. The work by Boone et al. shows that the addition of human or plant IDRs led to even more accumulation of MBD5/6 complexes at chromocenters. Furthermore, the removal of ACD proteins only partially reduced this accumulation phenotype. IDR- and ACD-mediated mechanisms can thus act combinatorially to induce high levels of protein multimerization and concentration in nuclear foci. View this paper
