Study Title | Biomolecular condensates create phospholipid-enriched microenvironments (Part 2) |
Study Type | Metabolomes of in vitro synthesized condensates |
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. These proteins included SARS-CoV-2 nucleocapsid, as well as low complexity domains of MED1 and HNRNPA1. |

Treatment Summary: | Mouse liver metabolites were combined with either the condensate-forming low-complexity domains of HNRNPA1, MED1 or full-length SARS-CoV-2 nucleocapsid. Condensates were stimulated with either 0 nM, 150 nM or 600 nM RNA. 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. Alternatively, liver metabolites were added 10 min after stimulating condensate formation with phage RNA and incubating for 2 min prior to centrifugation. In a separate set of experiments, the extraction procedure from the three fractions (ie aqueous, condensate and input) was altered to remove a heat step. |
