Random-phase-approximation theory for sequence-dependent, biologically functional liquid-liquid phase separation of intrinsically disordered proteins
Intrinsically disordered proteins (IDPs) are typically low in nonpolar/hydrophobic but relatively high in polar, charged, and aromatic amino acid compositions. Some IDPs undergo liquid-liquid phase separation in the aqueous milieu of the living cell. The resulting phase with enhanced IDP concentration can function as a major component of membraneless organelles that, by creating their own IDP-r...
متن کاملIntrinsically disordered linkers determine the interplay between phase separation and gelation in multivalent proteins
Phase transitions of linear multivalent proteins control the reversible formation of many intracellular membraneless bodies. Specific non-covalent crosslinks involving domains/motifs lead to system-spanning networks referred to as gels. Gelation transitions can occur with or without phase separation. In gelation driven by phase separation multivalent proteins and their ligands condense into den...
متن کاملIntrinsically disordered proteins.
Our understanding of protein function has been predominated by the view that proteins need to adopt a defined three dimensional structure to be able to carry out their function. Indeed, crystal structures of numerous proteins have been instrumental in establishing the structure– function paradigm. For example, the structures of numerous enzymes have highlighted the need for particular chemical ...
متن کاملIntrinsically disordered sequences enable modulation of protein phase separation through distributed tyrosine motifs
Liquid-liquid phase separation (LLPS) is thought to contribute to the establishment of many biomolecular condensates, eukaryotic cell structures that concentrate diverse macromolecules but lack a bounding membrane. RNA granules control RNA metabolism and comprise a large class of condensates that are enriched in RNA-binding proteins and RNA molecules. Many RNA granule proteins are composed of b...
متن کاملIntrinsically Disordered Proteins
In the same way that neither a messy lab bench nor a clean one is a reliable indicator of a researcher’s productivity, a protein’s function cannot be judged solely on the basis of its neatly folded and stable domains. As evidenced by recent work discussed in this Select, we are learning that intrinsically disordered regions feature in many of the cell’s most productive multitaskers, proteins wh...
