Summary: This study demonstrates the importance of weak interactions in the formation of condensates and provides a principle for rational protein design. By using a triblock approach, the propensity for condensate formation can be controlled by varying the weak dimerization of terminal blocks. The dissociation constants of the terminal domains directly correlate with the tendency for liquid-liquid phase separation. Additionally, differences in physical properties can be understood from the properties and interplay of constituent blocks.

Summary: We explored the design space for self-assembled multicomponent objects, ranging from unique building blocks to minimum number of distinct building blocks defining the target structure. By using patchy particle simulations, we analyzed the assembly dynamics of different solutions and their influence on the kinetics and yield of the target assembly. Our findings show that resource-saving solutions with minimum distinct blocks can perform just as well or faster than designs with unique building blocks. We also designed multifarious structures by sharing building blocks between different targets, and investigated the realization of multicomponent shapes using DNA nanostructures as building blocks through coarse-grained DNA simulations.

Summary: Protein-based hydrogels can mimic native extracellular matrices and have diverse applications in cell proliferation, drug/cell delivery, and tissue engineering. Light can be utilized as a regulation stimulus for modifying the mechanical and/or biochemical properties of these hydrogels. LOVTRAP, a light-responsive interaction between LOV2 and zdk1, has been used to engineer protein hydrogels whose viscoelastic properties can change in response to light, showing shear-thinning and self-healing properties. This new class of light-responsive protein hydrogels is expected to broaden the scope of dynamic protein hydrogels for biomedical applications.

Summary: This study investigated the mechanical and thermodynamic effects of two missense mutations, R57C-I94 and S22P-I84, in the elastic I-band part of cardiac titin. Results showed that R57C significantly destabilized the I94 module, while S22P led to only modest destabilization of I84. It is suggested that R57C may have a larger impact on titin elasticity compared to S22P.

Summary: Top7 is a de novo designed protein with atomic level accuracy that shows a non-cooperative folding process and involves various folding intermediate states. Fragments of Top7 can fold independently in isolation, but their folding pathways are influenced by interactions with neighboring sequences. This context-dependent folding behavior highlights the importance of intra-chain interactions in shaping the folding landscape of Top7, which may have implications for the design of novel proteins.
