γH2AX (gamma-H2AX) is a histone protein that plays a crucial role in the repair of DNA double-strand breaks (DSBs). It is a phosphorylated form of the H2AX protein, which is a component of chromatin.
γH2AX is often used as a biomarker for DNA damage and genomic instability. When DNA is damaged, the H2AX protein is phosphorylated, forming γH2AX, which recruits and activates DNA repair proteins to the site of damage.
γ-H2AX, a marker for DNA double-strand breaks.
Cancer cells often exhibit increased levels of γH2AX due to their high rate of DNA replication and repair errors.
Gamma-H2AX, on the other hand, refers to a phosphorylated form of H2AX.
