Formation of stres granules (SGs) has not yet been described in S. cerevisiae. We showed that robust heat shock induced accumulation of eIF3a/Tif32p/Rpg1p in cytoplasmic foci. They also contained eIF3b/Prt1p, eIF3c/Nip1p, eIF4G2, Pab1p, mRNA and small but not large ribosomes and eIF2a/Sui2p. Surprisingly, Dcp2p and Dhh1p P-body markers also co-localized with eIF3a, however, since formation of eIF3-accumulations required different scaffolding proteins than P-bodies, we suggest that they represent yeast specific SGs
