  • Phase Transitions Drive the Formation of Vesicular

    Expression of the individual viral components of the replication machinery in cells demonstrates that the 3 viral proteins required for replication are sufficient to drive cytoplasmic phase separation. Therefore, liquid liquid phase separation, previously linked to organization of P granules, nucleolus homeostasis, and cell signaling, plays a key role in host pathogen interactions.

  • Phase separation in the isolation and purification of

    Abstract. Phase separation is a simple, efficient, and cheap method to purify and concentrate detergent solubilized membrane proteins. In spite of this, phase separation is not widely used or even known among membrane protein scientists, and ready to use protocols are available for only relatively few detergent/membrane protein combinations.

  • Toward a better analysis of secreted proteins the example

    Abstract. Proteins are usually secreted at low concentrations in the culture media, which makes their recovery difficult. In addition, culture media are rich in salts and other compounds interfering with most proteomics techniques, which makes selective precipitation of proteins almost mandatory for a correct subsequent proteomics analysis.

  • Protein Phase Separation A New Phase in Cell Biology

    The concept of phase separation provides a new framework for our understanding of the functional role of sequence degeneracy (low complexity) and protein disorder. Accumulating evidence points to a key role for phase transitions in human diseases associated with protein aggregation, and to the misregulation of membraneless organelles in disease.

  • Phase separation of a yeast prion protein promotes

    Much recent work has focused on liquid liquid phase separation as a cellular response to changing physicochemical conditions. Because phase separation responds critically to small changes in conditions such as pH, temperature, or salt, it is in principle an ideal way for a cell to measure and respond to changes in the environment.
