Abstract Physical interactions between proteins are essential for most biological processes governing life 1 . However, the molecular determinants of such have been challenging to understand, even as genomic, proteomic and structural data increase.

Protein structures are essential to understanding cellular processes in molecular detail. While advances artificial intelligence revealed the tertiary structure of proteins at scale, their quaternary remains mostly unknown. We devise a scalable strategy based on AlphaFold2 predict homo-oligomeric assemblies across four proteomes spanning tree life.

Despite recent progress in computational strategies, de structures remains challenging, given vast size sequence-structure space. AlphaFold2 (AF2), a state-of-the-art neural network architecture, achieved remarkable accuracy predicting from amino acid sequences. This raises question whether AF2...

Abstract Predicting ligand-binding sites, particularly in the absence of previously resolved homologous structures, presents a significant challenge structural biology. Here, we leverage internal pairwise representation AlphaFold2 (AF2) to train model, AF2BIND, accurately predict small-molecule-binding residues given only target protein. AF2BIND uses 20 “bait” amino acids optimally extract binding signal small-molecule ligand. We find that AF2 pair outperforms other neural-network...
De novo protein design explores uncharted sequence and structure space to generate novel proteins not sampled by evolution. A main challenge in de involves crafting "designable" structural templates guide the searches toward adopting target structures.

Abstract Foamy viruses (FVs) constitute a subfamily of retroviruses. Their envelope glycoprotein (Env) drives the merger viral and cellular membranes during entry into cells. The only available structures retroviral Envs are those from human simian immunodeficiency orthoretroviruses, which distantly related to FVs. We report here cryo-EM FV Env ectodomain in pre- post-fusion states, demonstrate structural similarity with fusion protein (F) paramyxo- pneumoviruses, implying an evolutionary...
