We present the synthesis of a split-intein-mediated protein hydrogel. The building blocks of this hydrogel are two protein copolymers each containing a subunit of a trimeric protein that serves as a crosslinker and one half of a split intein. Mixing of the two protein copolymers triggers an intein trans-splicing reaction, yielding a polypeptide unit that self-assembles into a hydrogel. This hydrogel is highly pH- and temperature-stable, compatible with organic solvents, and easily incorporates...

Different methods to manipulate three-dimensional architecture in protein-based hydrogels are evaluated here with respect to material properties. The macroporous networks are functionalized with a cell-adhesive peptide, and their feasibility in cell culture is evaluated using two different model cell lines.
FAQs
The porous matrix creates a defined three-dimensional environment that can retain cells, enzymes, nucleic acids, and other expression components while allowing nutrients and substrates to diffuse inward. Newly synthesized proteins can also move through the network. This combination supports localized production while preserving access to materials required for transcription and translation.
Hydrogel composition determines the structural properties of the surrounding matrix and therefore helps control how expression components are held within it and how molecules move through the material. Tunable compositions allow researchers to examine how extracellular-like environments affect protein production and activity, rather than treating synthesis as independent of its physical surroundings.
Localization follows from retaining expression components within a defined region of the polymer network, while release depends on the movement of newly synthesized proteins through that matrix. By adjusting the material environment, researchers can investigate spatial and temporal patterns of functional protein availability. This is useful when protein position or timing matters as much as total production.
A setup may incorporate cells, enzymes, nucleic acids, or other components needed for protein expression, depending on the biological question. The selected materials are placed within a water-rich network that supports diffusion of nutrients and substrates. Researchers can then examine protein production within the defined matrix and evaluate how the environment affects the result.
These systems can provide information about gene expression, protein production, protein activity, and the spatial or temporal release of functional products. Because the expression process occurs within a structured material environment, researchers can also study how extracellular-like conditions influence those outcomes. The resulting measurements connect molecular synthesis with the physical properties of the surrounding matrix.
They are useful when researchers need to study protein production in a localized, three-dimensional setting or investigate how material structure influences biological function. Applications described for these systems include tissue engineering, biosensing, regenerative research, and studies of gene expression. Their ability to combine biomolecular synthesis with tunable matrix properties supports both mechanistic biology and biomaterial development.
