発明の名称 （英語） SUGAR-SENSING EPIGENOME BIOMARKER
発明の概要（英語） An antibody of the present invention specifically bonds to a serine 40 residue modified with N-acetylglucosamine (GlcNAc) in a histone H2A protein. The present invention provides a method for detecting GlcNAc-modification of a serine 40 residue in a histone H2A protein, said method having a step for measuring the level of GlcNAc-modification of the serine 40 residue in the histone H2A protein using the antibody. A protein or a peptide marker of the present invention is a marker for monitoring histone modification caused by fluctuations in the concentration of extracellular glucose, said marker comprising an H2A protein, or a peptide fragment thereof, that contains a GlcNAc-modified serine 40 residue.

[claim6]
6. The aforementioned histone H2A protein or GlcNAc conversion level of the ceric 40 residues of the peptide fragment, either of the claim 3-5 which is measured to GlcNAc of the histone H2A protein by the antibody which is connected to the ceric 40 residues which are converted uniquely in one section screening method of statement.
[claim7]
7. Being the method of monitoring the histone decoration which fluctuation of glucose density outside the cell causes,
The method of featuring that the process which measures the GlcNAc conversion level of the ceric 40 residues of the histone H2A protein which existence and depend of glucose it occurs is had.
[claim8]
8. GlcNAc conversion level of the ceric 40 residues of the aforementioned histone H2A protein, in the claim 7 which is measured to GlcNAc of the histone H2A protein by the antibody which is connected to the ceric 40 residues which are converted uniquely method of statement.
[claim9]
9. Being the marker which monitors the histone decoration which fluctuation of glucose density outside the cell causes,
The protein or peptide marker which features that to GlcNAc it includes the ceric 40 residues which are converted, consists of the H2A protein or the peptide fragment.
[claim10]
10. Being the method of appraising the stability of the genome DNA due to [epijieneteikusu] decoration,
The method of featuring that the process which measures the histone H2A protein or the GlcNAc conversion level of the ceric 40 residues of the peptide fragment is had.
[claim11]
11. The aforementioned histone H2A protein or GlcNAc conversion level of the ceric 40 residues of the peptide fragment, in the claim 10 which is measured to GlcNAc of the histone H2A protein by the antibody which is connected to the ceric 40 residues which are converted uniquely method of statement.
[claim12]
12. Being the marker which detects the stability of the genome DNA due to [epijieneteikusu] decoration,
The protein or peptide marker which features that to GlcNAc it includes the ceric 40 residues which are converted, consists of the H2A protein or the peptide fragment.
