In some embodiments, methods of detecting an association between a query protein and a target moiety are described. In some embodiments, compositions are described. In some embodiments, kits are described.

The present disclosure provides methods and pharmaceutical compositions for treating or slowing the progression of cancer, i.e., pancreatic cancer or esophageal cancer, by administering to a human subject in need thereof a therapeutically effective amount of an inhibitor of the histone methyltransferase, SETD2.

Provided herein are H1.0K180me2 antibodies, H1.0K180me2 proteins, and H1.0K180me2 peptides and methods of use for diagnostics and therapeutics. These H1.0K180me2 antibodies, H1.0K180me2 proteins, and H1.0K180me2 peptides may be used in the treatment of methylated H1.0-related diseases or conditions in an individual. These H1.0K180me2 antibodies, H1.0K180me2 proteins, and H1.0K180me2 peptides may also be used for the detection and quantification of a histone H1.0 protein or fragment thereof, comprising a dimethylated lysine at lysine residue 180 (H1.0K180me2); such compositions and methods are useful for detecting replicative senescence, DNA damage, genotoxic stress, radiation exposure, Alzheimer's disease, are useful for monitoring therapeutic regimens, patient stratification, drug screening, and may serve as a marker of biological aging in a system.

Provided herein are compositions and methods for improving immune system function. In particular, provided herein are compositions, methods, and uses of YY1 and EZH2 inhibitors for preventing and reversing T-cell exhaustion (e.g., for use in immunotherapy).

The presently disclosed subject matter relates to the administration of a KMT2D inhibitor for the treatment of a cancer. The present invention is based on the discovery that upon PI3K inhibition, KMT2D activity is upregulated, resulting in an increase in the expression of genes involved in breast cancer cell proliferation and tumor growth. Accordingly, the present invention provides methods for treating a subject that has cancer by administering a therapeutically effective amount of an KMT2D inhibitor.

The present disclosure provides compositions with a modulating gene expression and methods for modulating transcription.

Provided herein are compositions and methods related to the production and detection of a histone H1.0 protein dimethylated at lysine residue 180 (K180) (H1.0K180me2 protein) or a histone H1.0 peptide dimethylated at a lysine residue corresponding to K180 (H1.0K180me2 peptides). The H1.0K180me2 protein and H1.0K180me2 peptides are useful for applications including, but not limited to, molecular diagnostics of DNA damage, genotoxic stress, radiation exposure, and Alzheimer's disease, therapeutics, monitoring of therapeutic regimens, patient stratification, and drug screening. Also provided herein are antibodies specific for the H1.0K180me2 protein and H1.0K180me2 peptides.

Provided herein are fusion proteins comprising a catalytically inactive Cas9 domain and an effector domain. The fusion proteins of the present invention can be used to, for example, produce epigenetic modifications at target chromatin sites. Nucleic acids and expression vectors encoding the fusion proteins, as well as cells comprising the fusion proteins, are also provided herein.

A method for promoting the reprogramming of a non-cardiomyocytic cell or tissue into cardiomyocytic cell or tissue comprising is carried out by contacting a non-cardiomyocytic cell or tissue with a modulator of histone methyltransferase activity or expression.

Provided herein are polypeptides containing stabilized therapeutic peptides related to enhancer of zeste homolog 2 (EZH2), histone lysine N-methyltransferase. Also provided are compositions containing these polypeptides and methods of using such peptides in the treatment of cancer that include administering to a subject one of the polypeptides.
