Gene Information

human ... H2AFX(3014)

General description

H2AFX/H2AX (H2A histone family member X) codes for a key histone, that belongs to the histone H2A gene family. It is located on human chromosome 11q23.3.
Histones are basic nuclear proteins that are responsible for the nucleosome structure of the chromosomal fiber in eukaryotes. Two molecules of each of the four core histones (H2A, H2B, H3, and H4) form an octamer, around which approximately 146 bp of DNA is wrapped in repeating units, called nucleosomes. The linker histone, H1, interacts with linker DNA between nucleosomes and functions in the compaction of chromatin into higher order structures. This gene encodes a member of the histone H2A family, and generates two transcripts through the use of the conserved stem-loop termination motif, and the polyA addition motif. (provided by RefSeq)

Immunogen

H2AFX (AAH04915, 1 a.a. ~ 143 a.a) full-length recombinant protein with GST tag. MW of the GST tag alone is 26 KDa.

Application

Monoclonal Anti-H2AFX antibody has been used in western blotting.

Biochem/physiol Actions

H2AFX (H2A histone family member X) participates in the detection of DNA double-stranded breaks that can lead to translocations. Mutations in H2AFX gene results in non–hodgkin lymphoma.

Physical form

Solution in phosphate buffered saline, pH 7.4

A-type lamins encoded by LMNA form a structural fibrillar meshwork within the mammalian nucleus. How this nuclear organization may influence the execution of biological processes involving DNA transactions remains unclear. Here, we characterize changes in the dynamics and biochemical interactions
