Comprehensive understanding of compound selectivity across diverse epigenetic reader families is critical for effective drug discovery and mechanistic elucidation. CD BioSciences provides an integrated multiple domains screening service, enabling simultaneous profiling of key reader domains—such as bromodomains, chromodomains, tudor, MBT, PHD, and SRA domains—to deliver actionable insights into polypharmacology and off-target effects, accelerating your path from screening to validated leads.
The functional diversity of epigenetic reader domains—such as bromodomains, chromodomains, Tudor, MBT, PHD, and SRA domains—lies in their specific recognition of distinct histone modifications and their cooperative roles within gene regulatory networks. In modern epigenetic drug discovery, there is a growing emphasis on compound selectivity and multi-target synergies, highlighting the limitations of single-domain screening approaches. Integrated multi-domain screening is therefore essential, as it enables the simultaneous assessment of compound activity across various reader families, facilitating selective optimization, multi-target pharmacology studies, and early-stage evaluation of potential off-target effects.

As a pioneer in epigenetic drug discovery services, CD BioSciences offers industry-leading integrated multi-domain screening solutions capable of simultaneously analyzing multiple epigenetic reader domains to comprehensively characterize compound selectivity. This approach accelerates the discovery of multi-target drugs and deepens our understanding of epigenetic regulatory mechanisms.
At CD BioSciences, we provide a fully integrated, one-stop solution for comprehensive epigenetic reader domain screening. Our platform enables parallel profiling of compounds against multiple domains within a single, streamlined workflow. This approach not only delivers a holistic view of compound selectivity and polypharmacology but also significantly reduces project timelines by consolidating what would traditionally require multiple separate screening campaigns.
We support both individual and combined screening for the six major classes of epigenetic reader domains:
| Domain Types | Function | Representative Protein Targets |
|---|---|---|
| Bromodomain | Recognizes acetylated lysine residues. |
|
| Chromodomain | Recognizes methylated lysine residues. |
|
| Tudor Domain | Recognizes methylated lysine/arginine. |
|
| MBT Domain | Recognizes mono-/dimethylated lysine. |
|
| PHD Finger | Recognizes methylated lysine. |
|
| SRA Domain | Recognizes methylated cytosine (in DNA). |
