Q & A

What is the primary function of proteins in our bodies?

Proteins serve as the workhorses of our bodies, performing a wide range of functions from aiding in cell growth to maintaining the smooth operation of our immune systems, and are central to nearly every biological process.

How do proteins interact with each other?

Proteins interact with each other by binding, similar to a key fitting into a lock, which allows for the execution of critical functions within our cells.

What is AlphaFold and what does it do?

AlphaFold is an AI model that predicts how proteins interact with each other, providing a solid understanding of their binding interactions, which has been significant for scientific research.

How does AlphaProto differ from AlphaFold?

While AlphaFold is adept at predicting protein interactions, AlphaProto goes a step further by designing entirely new proteins that can bind to specific target molecules.

What are the potential applications of AlphaProto's designed proteins?

AlphaProto's designed proteins, also known as binders, can accelerate research in drug discovery, disease understanding, and enhancing crop resistance to pests.

How does AlphaProto create a protein that binds to a target?

AlphaProto uses its training on extensive protein data to design a binder protein that fits a target almost perfectly, given the structure of the target protein.

What was the success rate of AlphaProto's binders in lab tests?

AlphaProto's binders demonstrated a success rate of 3 to 300 times better binding strengths compared to existing methods, with 88% of candidate binders successfully binding to the bhrf1 protein in lab tests.

How does AlphaProto contribute to the fight against diseases like COVID-19?

AlphaProto has designed binders for the SARS-CoV-2 Spike protein, which were confirmed by research groups to block the virus and some of its variants from infecting cells, potentially aiding in virus prevention.

What is ORB and how does it relate to material science?

ORB is an AI model designed to simulate materials at the atomic level more quickly and accurately than existing alternatives, significantly advancing material science research.
