Table 1.
Oligomerization domains present in PB and SG components. Oligomerization or dimerization domains relevant for foci formation were identified by deletion of distinct protein regions, or by fusion to reporter proteins. The oligomerization/dimerization domains are conserved in the species listed. The knockdown of molecules carrying the indicated aggregation domains affects foci formation in several cases. Similar putative dimerization/oligomerization domains present in additional PB components, including FMRP and CPEB, are present [46], [190], [194].
