01 / Our science

Curiosity at the
molecular scale.

We bring together small-molecule discovery, chemical proteomics, and functional genomics to reveal new biology and open paths to drug discovery.

Conceptual workflow from chemical probes to proteome-wide target engagement. No experimental measurements are shown.

01 / Chemical proteomics

Chemical Proteomics & Covalent Ligand Discovery

We design chemically and stereochemically diverse small molecules to explore ligandable sites in native biological systems.

Conceptual perturbation-to-mechanism workflow. Screening and validation are illustrated, not measured.

02 / Functional genomics

Functional Genomics & Mechanism of Action

We combine CRISPR screening with focused genetic perturbations to connect compound activity to its biological mechanism.

Conceptual overview of ligand binding, protein modulation, and cellular response. No experimental results are depicted.

03 / Protein modulation

Protein Modulation & Disease Biology

A ligand can do more than block an active site.

A chemical handle
on transcription.

How can a small molecule change the fate of a protein in the transcription machinery? Our work identified covalent degraders of ERCC3 / XPB, a key component of TFIIH.

From chemical discovery to protein fate

01

Start with small molecules.

Spirocycle acrylamide stereoprobes explore new chemical space.

02

Read the proteome.

Chemical proteomics maps covalent engagement of ERCC3 / XPB.

03

Resolve the mechanism.

Genetic disruption of FBXL18 blocks ERCC3 degradation by ZL-12A.

One target, distinct outcomes: ZL-12A and triptolide engage the same cysteine but produce different protein degradation profiles.
