Bioactivity and enzyme data
Enzyme cohort genes (≥1 EC): 1.
Cohort genes with ChEMBL bioactivity (full, sorted by assay count)
| Symbol | Assays | Type breakdown |
|---|---|---|
| DSP | 2 | Binding:2 |
| TTN | 1 | Binding:1 |
| PMS2 | 1 | Binding:1 |
Cohort enzymes (BRENDA EC)
| Symbol | EC numbers | Names |
|---|---|---|
| TTN | 2.7.11.1 | non-specific serine/threonine protein kinase |
Pharmacogenomics
Cohort genes with a PharmGKB record: 9; with CPIC/DPWG dosing guidelines: 0.
No cohort gene has a CPIC/DPWG genotype-guided dosing guideline (PharmGKB).
Chemical tractability of cohort targets
0 approved/phased compounds have measured bioactivity against a cohort gene (and aren’t yet in disease-level trials). This is a research / tractability signal, NOT a therapeutic recommendation — a bioactivity row often reflects off-target or screening binding (e.g. promiscuous kinase inhibitors against a cohort kinase), implying no disease mechanism.
Druggability pyramid
Cohort genes binned by druggability tier (high → low):
| Tier | Definition | Genes | Symbols |
|---|---|---|---|
| A | Approved (phase 4 drug) | 0 | |
| B | Phased (≥1) drug, not yet approved | 0 | |
| C | Druggable family + PDB, no drug | 1 | TTN |
| D | Druggable family + AlphaFold only, no drug | 2 | CORIN, CCDC141 |
| E | Difficult family or no structure, no drug | 8 | PLEKHA3, DSP, FKBP7, TTN-AS1, CYLD-AS1, LRP4, PMS2, PRKRA |
