Design of intrinsically disordered proteins that undergo phase transitions with lower critical solution temperatures

Many naturally occurring elastomers are intrinsically disordered proteins (IDPs) built up of repeating units, and they can demonstrate two types of thermoresponsive phase behavior. Systems characterized by lower critical solution temperatures (LCSTs) undergo phase separation above the LCST, whereas systems characterized by upper critical solution temperatures (UCSTs) undergo phase separation below the UCST. There is congruence between...
