Characteristics of RNAs enriched in RNA granules.

RNA Granule	Enriched RNAs (Examples)	Depleted RNAs (Examples)	Prefer Long mRNAs?	Prefer Translationally Repressed mRNAs?
P-bodies	Translationally repressed mRNAs [17]	18S and 28S rRNAs [17]	N/A	Yes
Stress granules	mRNAs with longer coding regions and 3′UTRs [29,37] lncRNAs [29] 18S rRNA [124]	Membrane-associated mRNAs [29] gapdh [29] 28S rRNA [124]	Yes	Yes
P granules (C. elegans)	Long mRNAs with low ribosome occupancy [67] Germ-cell specific mRNAs [67]	N/A	Yes	Yes
Polar granules (D. melanogaster)	Germ-cell specific mRNAs [49,87,125]	oskar [49,125]	N/A	Yes, but with exceptions [58,59,87,105,108,109,110,111]
