Assembly of Signaling Complexes

Assembly of Signaling Complexes

Multiprotein signaling complexes are formed in a dynamic process involving protein-protein interactions at the cytoplasmic domain of transmembrane receptors or enzymatic and non-enzymatic proteins associated with the receptor. These complexes ensure the activation and propagation of intracellular signals that regulate cell functions.
Interaction domains in cell signaling
Interaction domains recognize exposed features of their binding partners containing post-translationally modified sequences,...

Conserved Binding Sites

Conserved Binding Sites

Many proteins’ biological role depends on their interactions with their ligands, small molecules that bind to specific locations on the protein known as ligand-binding sites. Ligand-binding sites are often conserved among homologous proteins as these sites are critical for protein function.
Binding sites are often located in large pockets, and if their location on a protein’s surface is unknown, it can be predicted using various approaches. The energetic method computationally...

Protein-protein Interfaces

Protein-protein Interfaces

Many proteins form complexes to carry out their functions, making protein-protein interactions (PPIs) essential for an organism's survival. Most PPIs are stabilized by numerous weak noncovalent chemical forces. The physical shape of the interfaces determines the way two proteins interact. Many globular proteins have closely-matching shapes on their surfaces, which form a large number of weak bonds. Additionally, many PPIs occur between two helices or between a surface cleft and a...

Neural Circuits

Neural Circuits

Neural circuits and neuronal pools are two of the main structures found in the nervous system. Neural circuits are networks of neurons that work together to carry out a specific task or process. They consist of interconnected neurons and glial cells, which provide structural and metabolic support.
Neuronal pools are collections of nerve cells with similar functions and interact through chemical and electrical signals. These pools include both interneurons (the central neural circuit nodes that...

Background:

Protein function relies on specific residues within a stable structure.
Designing novel proteins with desired functions is a significant challenge.
Current methods often require predefined protein folds or structures.

Purpose of the Study:

To develop deep learning methods for de novo protein scaffold design.
To create functional protein sites without prespecifying scaffold architecture.
To generate diverse protein designs including immunogens, enzymes, and binding proteins.

Main Methods:

Introduced 'constrained hallucination' to optimize sequences for desired functional sites.
Developed 'inpainting' to build scaffolds around functional sites using RoseTTAFold.
Applied these methods to design various functional proteins.

Main Results:

Successfully designed candidate immunogens, receptor traps, metalloproteins, enzymes, and protein-binding proteins.
Validated designs through a combination of in silico predictions and experimental testing.
Demonstrated the ability to create functional protein scaffolds without predefined folds.

Conclusions:

Deep learning offers powerful tools for de novo protein scaffold design.
These methods enable the creation of novel proteins with tailored functions.
The developed approaches have broad applications in biotechnology and protein engineering.
