Step-by-step how to run FlashPPI on your favorite genomes!

Predicting protein-protein interactions (PPIs) at proteome scale can take months with co-folding models due to the massive all-vs-all comparisons required.

We are excited to announce FlashPPI, a contrastive learning framework that predicts proteome wide physical interfaces in minutes. 1/🧡

SeqHub - The Home for Biological Sequences SeqHub is a platform for exploring, annotating, and sharing biological sequences.

For a typical microbial genome, all-vs-all PPI prediction with AF3 would take hundreds of GPU-years. With FlashPPI, we can scale molecular interaction prediction across diverse, non-model microbial genomes, unlocking truly scalable discovery. We deployed FlashPPI on Seqhub.org, give it a spin!

3. Online hard negative mining improves sensitivity.
We use joint optimization to let the model propose hard negatives for contact prediction during training. This results in even more sensitive and robust performance.

2. Learning how proteins interact matters
It's not enough to learn that 2 proteins interact, learning *how* they interact at residue level is critical for performance.

Some fun highlights on what we learned along the way:
1. Reframing PPI prediction as retrieval
Instead of asking β€œDo A and B interact?”, we ask: Which proteins does A interact with in this genome? This shift in framing enables linear-time scaling and ultrafast performance.

Protein–protein interactions (PPIs) are key to discovering and interpreting new biological functions.

We’re excited to introduce 𝑭𝒍𝒂𝒔𝒉𝑷𝑷𝑰: a new application of gLM2 that uses genomic language modeling to predict proteome-wide PPIs in microbial genomes in minutes.

We’d love to join your lab meeting!

We’ve been meeting with research groups to share how scientists are using SeqHub for sequence and genome analysis, and the conversations have been highly interactive and grounded in real workflows.

Booking info below.

Hi Roland, our servers are in the US, we explicitly state in our docs that we do not train models on private data, and the data is private to you only - unless intentionally made public (for publication/data sharing purposes)!

thanks for the feedback! We are working on making more of the platform exportable as figures😊

Released today from Tatta Bio: SeqHub! A place to explore, annotate, and share sequence data with functional insights.Β 

Over 1,000 scientists worldwide have already used SeqHub to annotate more than 550,000 proteins, uncovering new insights and accelerating discovery.

Annotations are mapped using embedding-based search, making it faster than most alignment-based search. HMM prediction speed-up comes from some optimization and parallelization :)

SeqHub SeqHub is a platform for exploring, annotating, and sharing biological sequences.

Currently, SeqHub is optimized for microbial protein and genome analysis. As we expand beyond microbial data, we'd love your feedback to help shape what comes next. I'm deeply grateful to our team at Tatta Bio, and to our collaborators and funders, for making this vision a reality. πŸ”— seqhub.org

Today's sequence data infrastructure is set up for failure in the age of AI. Building an open and collaborative sequence platform for both Human and AI scientists.

At Tatta Bio, we have been thinking deeply about the sequence-to-function problem. We believe that before AI can power functional prediction, we first need to rethink how we curate, manage, and share sequence data. Here, we share our initial ideas on what we are building next:

Assemblies of long-read metagenomes suffer from diverse errors Genomes from metagenomes have revolutionised our understanding of microbial diversity, ecology, and evolution, propelling advances in basic science, biomedicine, and biotechnology. Assembly algorithms...

I am very happy (and anxious) to share with you our most recent work in which we evaluated four of the most popular long-read assemblers,
