Before revision: Many intrinsically disordered proteins (IDPs) , proteinsthat do not fold into a unique tertiary structure in isolation because of their depletion in hydrophobicity whereas enrichment in charge and aromaticity, retain their structural disorderness when participating in IDP-IDP binding andIDP phase separation via a sequence-specific "fuzzy  " molecular recognition mechanism.
After revision: Many intrinsically disordered proteins (IDPs) are important for biological functions. In contrast to folded proteins, molecular recognition among certain IDPs is "fuzzy " molecular recognition mechanism.
