Summary
PWWP2B (PWWP domain containing 2B, HGNC:25150) is a protein-coding gene on chromosome 10q26.3, encoding PWWP domain-containing protein 2B (Q6NUJ5). Chromatin-binding protein that acts as an adapter between distinct nucleosome components (H3K36me3 or H2A.Z) and chromatin-modifying complexes, contributing to the regulation of the levels of histone acetylation at actively transcribed genes.
Enables NuRD complex binding activity. Predicted to be involved in chromatin remodeling; positive regulation of transcription elongation by RNA polymerase II; and regulation of cold-induced thermogenesis. Located in nucleoplasm.

Literature-anchored findings (GeneRIF, showing 2)
- Study in HeLa, HEK293F, and mouse embryonic stem cells reveal that loss of PWWP2A/B leads to increases in histone acetylation predominantly at highly expressed genes, accompanied by decreases in Pol II elongation. Collectively, these findings suggest a role for PWWP2A/B in regulating transcription through the fine-tuning of histone acetylation dynamics at actively transcribed genes. (PMID:30228260)
- PWWP2B promotes DNA end resection and homologous recombination. (PMID:35582821)

Function. Chromatin-binding protein that acts as an adapter between distinct nucleosome components (H3K36me3 or H2A.Z) and chromatin-modifying complexes, contributing to the regulation of the levels of histone acetylation at actively transcribed genes. Competes with CHD4 and MBD3 for interaction with MTA1 to form a NuRD subcomplex, preventing the formation of full NuRD complex (containing CHD4 and MBD3), leading to recruitment of HDACs to gene promoters resulting in turn in the deacetylation of nearby H3K27 and H2A.Z. Plays a role in facilitating transcriptional elongation through regulation of histone acetylation. Negatively regulates brown adipocyte thermogenesis by interacting with and stabilizing HDAC1 at the UCP1 gene promoter, thereby promoting histone deacetylation at the promoter leading to the repression of UCP1 expression.
Subunit / interactions. Component of a MTA1-specific subcomplex of the NuRD complex composed of PWWP2B, MTA1 and HDAC1 but does not contain CHD4 and MBD3. Interacts with MTA1 and HDAC1. Interacts with MTA2, MTA3, HDAC2, RBBP4, RBBP7, BRCC3 and ZNF516. Does not interact with CHD4 and MBD3.
Post-translational modifications. Deubiquitinated by BRCC3; leading to its stabilization.

Is drug target: yes
ChEMBL targets (1): CHEMBL6066163 (SINGLE PROTEIN)
Molecules with ChEMBL bioactivity
1 molecules (phase ≥1), by development phase (incl. off-target/promiscuous compounds). Patent mentions across the top 20 by phase: 1,538 (via chembl_molecule»patent_compound — counts attach to the compound, not the gene–compound relationship, so off-target/promiscuous molecules can dominate).
| Molecule | Name | Phase | Patents |
|---|---|---|---|
| CHEMBL1232461 | MOLIBRESIB | 2 | 1,538 |
PharmGKB: 1 entry (VIP=true, CPIC=false)
ChEMBL bioactivities
2 potent at pChembl≥5 of 2 total, top 2 by pChembl (potency: 10 = 0.1 nM, 6 = 1 µM).
| pChembl | Type | Value | Unit | Molecule |
|---|---|---|---|---|
| 7.60 | Kd | 25 | nM | MOLIBRESIB |
| 7.40 | IC50 | 40 | nM | MOLIBRESIB |
PubChem BioAssay actives
2 with measured affinity, of 7 total; 1 most potent distinct compounds. Largely complementary to BindingDB; screening values are coarse (µM, 4 dp), so sub-nM hits tie at the floor.
| Compound | Assay | Type | Value | Unit |
|---|---|---|---|---|
