Study Title | Biomolecular condensates create phospholipid-enriched microenvironments (Part 4) |
Study Summary | Proteins and RNA are able to phase separate from the aqueous cellular environment to form sub-cellular compartments called condensates. This process results in a protein-RNA mixture that is chemically distinct from the surrounding aqueous phase. Here we use mass spectrometry to characterize the metabolomes of condensates. To test this, we prepared mixtures of phase-separated proteins and cellular metabolites and identified metabolites enriched in the condensate phase. Here, we confirmed the presence of lipids in MED1 samples and condensates using reversed-phase LC-MS. |

Treatment:
Treatment ID: | TR002860 |
Treatment Summary: | Mouse liver metabolites were combined with the condensate-forming low-complexity domain of MED1. Condensates were stimulated with 150 nM RNA and then incubated for 10 min. In a subset of samples, RNA addition occurred 10 min before metabolite addition. Next, condensates were centrifuged to the bottom of a 600 ul tube. Equal fractions from the input sample, aqueous phase and condensate phases were collected separately. Metabolites were extracted from each fraction using 80% methanol in steps that involved disrupting condensates with heat. In a subset of samples, this heat step was omitted. |
