Histone H3 mutant markers
Your guide to studying histone H3 mutations in cancer.
We've put together a quick overview of the most common histone mutations affecting histone 3 (H3) - H3K27M, H3K36M, H3G34 (W/V/R) - so you can easily find the right tools to study your histone mutant.
Histone mutations in cancer
Recurrent histone mutations have been recently described in various cancer types, including brain tumors, chondroblastoma, giant cell tumors of bone, and leukemia. Current research suggests that histone mutations alter the epigenetic landscape, but underlying mechanisms are not completely understood.
The identification of widespread recurrent driver mutations in histones has raised significant interest in the development of novel targeted epigenetic therapies for histone mutant tumors, as well as biomarkers for diagnostics and monitoring of drug response.
Here we review the five common histone mutations affecting H3 - H3K27M, H3K36M, and H3G34 (W/V/R) - and recommend our best recombinant monoclonal antibodies to study these targets.
H3K27M
H3K27M mutations are found in pediatric brain tumors and adult cancers, such as acute myeloid leukemia, melanoma, and glioma1. H3K27M acts as a suppressor of the PCR2 complex, leading to a global reduction of H3K27 di- and trimethylation levels (H3K27me2 and H3K27me3)2.
Applications: WB, Indirect ELISA, IHC-P, ICC/IF, IP, ChIP
We recommend
Recombinant anti-H3K27M antibody - ChIP Grade (ab190631)

H3K36M
H3K36M is a potential oncogenic driver mutation in chondroblastomas; also found in pediatric soft tissue sarcomas and HNSCC. Similar to H3K27M, the H3K36M mutation suppresses the methyltransferase activity of SETD2 and NSD family proteins and leads to the global reduction of H3K36 di- and trimethylation levels1.
Applications: IP, WB, IHC-P, ICC/IF, Flow Cyt, Indirect ELISA.
We recommend
Recombinant anti-H3K36M antibody (ab256384)

H3G34W
H3G34W mutation is a substitution of glycine 34 with tryptophan (G34W); it's a high-frequency mutation (>90%) in giant cell tumor of bone (GCTB).
In GCTB, H3.3G34W expression was shown to promote cellular proliferation in-vitro by inducing transcriptional deregulation and splicing alterations1.
Applications: ChIP, WB, ICC/IF, Flow Cyt, Dot blot, IHC-P.
We recommend
Recombinant anti-histone H3.3 (mutated G34W) antibody - ChIP Grade (ab272691)
References
H3G34V
H3G34V mutation is a substitution of glycine 34 with valine (G34V). H3G34V/R mutations are predominantly found in high-grade gliomas of children and adolescents and are associated with loss-of-function mutations in p53 and ATRX, as well as with the deregulated expression of N-Myc protein1.
Applications: WB, ICC/IF, Flow Cyt, Dot blot, ChIP, IHC-P.
We recommend
Recombinant anti-histone H3.3 (mutated G34V) antibody- ChIP Grade (ab254401)
References
H3G34R
H34G34R mutation is a substitution of glycine 34 with arginine (G34R).
H3G34V/R mutations are predominantly found in high-grade gliomas and are associated with loss-of-function mutations in p53 and ATRX1.
We recommend
Recombinant anti-histone H3.3 (mutated H3G34R) antibody - ChIP Grade (ab254402)
