In the realm of artificial intelligence, AlphaFold once reigned supreme in protein prediction. However, it now welcomes a new companion—AlphaSeq. This database, launched by A-Alpha Bio, not only breaks through the limitations of AlphaFold but also opens up new horizons in the study of protein-protein interactions (PPI).
AlphaFold has achieved remarkable success in predicting protein structures, but it has struggled with PPI predictions. The complexity of PPI prediction is akin to an insurmountable wall. Yet, A-Alpha Bio's AlphaSeq database is like a brave climber who has successfully scaled this formidable barrier.

AlphaSeq contains over 750 million measurement results, making it the world's largest PPI dataset. This vast dataset not only provides rich training material for the AlphaBind model but also enhances the precision of protein design and the discovery of new proteins.
What's even more astonishing is that AlphaSeq's experimental platform can simultaneously quantify the binding affinity of millions of PPIs and deliver results rapidly. This scalable capability is akin to a super accelerator, propelling the pace of protein research faster and further.
The strength of A-Alpha Bio is not to be underestimated. They not only have computational biology expert David Baker as a scientific advisor but also a group of talented co-founders. Their technology stems from a 2017 paper published by the Baker lab, which described the fundamental methods for large-scale collection and characterization of PPI data.
The principle of AlphaSeq actually originates from the pairing process of yeast cells. Researchers ingeniously utilize this natural phenomenon, through genetic modification, where the strength of protein interactions determines the likelihood of yeast cell pairing. This innovative method not only simplifies and expedites the measurement of protein interactions but also opens new avenues for protein research.
Although AlphaSeq has not yet released its latest paper, and information about the AlphaBind model is limited, its application prospects are undoubtedly vast. Whether it's designing drugs like immunocytokines or collaborating with major pharmaceutical companies to develop "molecular glue," AlphaSeq shows tremendous potential.
In this era of artificial intelligence and big data, the emergence of AlphaSeq and the AlphaBind model is not just a symbol of technological progress, but a great leap forward in humanity's quest to unravel the mysteries of life. Let's look forward to how these AI assistants will continue to unveil the enigmatic veil of life.
