Tools

One protein, one question. Every free, in-browser tool — filter by who you are, what kind, and status.

Each tool has one craft: a way of knowing

The crafts are ways of knowing, shown as craftspeople. They are never protein faces: the craftspeople do the work, and the proteins only get bumped about.

    Pockets

    Where could a drug bind?

    A geometric binding-pocket finder — cavities ranked by a transparent heuristic. Geometry, not a druggability predictor.

    Live

    with the Doubter · A hollow in a shape is a guess at a pocket, not proof that anything binds there.

  • Interfaces

    Where do two chains touch?

    Find the epitope/paratope interface of a complex from geometry. A geometric contact map, not an experimentally-mapped epitope.

    Live

    with the Photographer · You read where two measured chains touch in a real experimental structure.

  • Variants

    What does this mutation change?

    A phenotype → causal-gene → protein-structure explorer over well-established monogenic conditions. Not a predictor or diagnostic.

    Live

    with the Tailor · One changed letter in a gene, and where it lands on the protein.

  • Families

    How much does one protein change across life?

    One protein across a ladder of organisms, compared with ours letter by letter and by predicted shape. Every entry is looked up, never typed. Not a phylogeny.

    Live

    with the Tailor · The same protein in many organisms, compared letter by letter.

    PoreSort

    What gets through the pore?

    Predict which particles pass real channels (aquaporin-1, GLUT4, CFTR), then see the live AlphaFold structure. A pore is not a wall with a doorman.

    HingeHunt

    Do you trust where the domains sit?

    A model can be crisp everywhere and still be unsure how its domains are arranged. Judge the arrangement, then read the real PAE.

    Live

    with the Doubter · Crisp parts, and still a question: how sure is their arrangement?

    P04637 · cartoon, coloured by confidence · prediction

    DisorderDuty

    Is that floppy bit broken or working?

    Low-confidence regions are usually intrinsically disordered — and doing a job. Tag each region, then see the live UniProt annotation.

    Live

    with the Sketcher · A faint part of the drawing is often a floppy part that still has a job.

    FlexiFit

    Rigid keyhole, or does it reshape?

    Binding pockets are rarely rigid keyholes — many reshape on contact (induced fit). Predict rigid vs reshapes for real enzymes.

    Live

    VanishPoint

    What survives when you only trust what the model is sure of?

    Drag AlphaFold's confidence lens and watch a protein fade. Predict where each region vanishes — and learn that a faded region is usually flexible and functional, not a mistake.

    Can you carve a chain into its domains — and trust how they sit?

    Carve a protein into its folded domains, then use AlphaFold's PAE to judge how much to trust where those domains sit relative to each other.

    BuriedBet

    Which face does a protein hide against its partner?

    PencilOrInk

    Where should a protein be drawn sketchy?

    You are the renderer: choose which parts of a protein to draw in firm ink and which to draw sketchy. Sketchy is not wrong — it is how you honestly draw a flexible, functional region.

    Live

    with the Sketcher · You draw the parts: firm ink where the model is sure, pencil where it is not.

    SpliceSplit

    How does one gene make different proteins?

    Compare two spliced isoforms of one gene and pick the exon that explains the difference. Splicing makes different chains — not one chain morphing into several shapes.

    NotMarbles

    Is a protein really a solid ball of marbles?

    with the Jostler · Atoms jiggle; some parts smear more than others.

  • The protein-structure pathway

    Where should I start, and what comes next?

    NumberReader

    What do AlphaFold's real confidence numbers say?

    Read the real confidence numbers off human haemoglobin: guess how sure the model is for a region, then see its actual per-residue pLDDT and pairwise PAE — computed live from the model — and learn to say it plainly: a prediction, not an experiment.
