Area of Science:

Protein engineering
Structural biology
Molecular recognition

Background:

Shape complementarity is crucial for molecular recognition.
Tailoring binding scaffold shapes can enhance protein reagent and therapeutic development.

Purpose of the Study:

To develop a general method for controlling the shape of binding surfaces on repeat-protein scaffolds.
To apply this approach to leucine-rich-repeat proteins.

Main Methods:

Designing self-compatible building-block modules for polymerization into surfaces with controlled curvatures.
Developing junction modules to connect these building blocks.
Combining modules to create proteins with custom-designed shapes.

Main Results:

Demonstrated a general approach to control binding surface shape in repeat proteins.
Successfully applied the method to leucine-rich-repeat proteins.
Crystal structures confirmed the ability to engineer specific protein curvatures.

Protein Folding

Protein Folding

Proteins are chains of amino acids linked together by peptide bonds. Upon synthesis, a protein folds into a three-dimensional conformation, critical to its biological function. Interactions between its constituent amino acids guide protein folding, and hence the protein structure is primarily dependent on its amino acid sequence.

Mechanisms of Membrane-bending

Mechanisms of Membrane-bending

The living membranes are flexible due to their fluid mosaic nature; however, their bending into different shapes is an active process regulated by specific lipids and proteins. The membrane bending can be transient as seen in vesicles or stable for a long time as in microvilli. Cells regulate the size, location, and duration of the membrane curvature.
Membrane bending can happen due to intrinsic changes in lipid composition or extrinsic association with different proteins. The proteins involved...

Protein Folding Quality Check in the RER

Protein Folding Quality Check in the RER

ER is the primary site for the maturation and folding of soluble and transmembrane secretory proteins. The calnexin cycle is a specific chaperone system that folds and assesses the confirmation of N-glycosylated proteins before they can exit the ER lumen. The primary players of this quality check pipeline are the lectins, ER-resident chaperones, and a glucosyl transferase enzyme. In case the calnexin system in the lumen fails to salvage a misfolded protein, it is transported to the cytoplasm...

Conservation of Protein Domains Over Different Proteins

Conservation of Protein Domains Over Different Proteins

Protein domains are small structurally independent units that are part of a single amino acid chain. Although these domains are often structurally independent, they may rely on synergistic effects to perform their functions as part of a larger protein. Protein domains may be conserved within the same organism, as well as across different organisms.
A limited set of protein domains often duplicate and recombine during evolution. These domains can be organized in different combinations to...
