Fe65 plays a central role in the response to DNA damage by translocating to the nucleus and inducing apoptosis. May act by specifically recognizing and binding histone H2AX phosphorylated on 'Tyr-142' (H2AXY142ph) at double-strand breaks (DSBs), recruiting other pro-apoptosis factors such as MAPK8/JNK1.Required for histone H4 acetylation at double-strand breaks (DSBs).Its ability to specifically bind modified histones and chromatin modifying enzymes such as KAT5/TIP60, probably explains its trancription activation activity.http://www.ncbi.nlm.nih.gov/protein/Q9QXJ1.2?ordinalpos=6&itool=EntrezSystem2.PEntrez.Sequence.Sequence_ResultsPanel.Sequence_RVDocSum | Fe65 plays a central role in the response to DNA damage by translocating to the nucleus and inducing apoptosis.

[SUBCELLULAR LOCATION] Cell membrane. Cytoplasm. Nucleus. Note=In | |||
normal conditions, it mainly localizes to the cytoplasm, while a | |||
small fraction is tethered to the cell membrane via its interaction | |||
with APP. Following exposure to DNA damaging agents, it is released | |||
from cell membrane and translocates to the nucleus. Nuclear | |||
translocation is under the regulation of APP.http://www.ncbi.nlm.nih.gov/protein/Q9QXJ1.2?ordinalpos=6&itool=EntrezSystem2.PEntrez.Sequence.Sequence_ResultsPanel.Sequence_RVDocSum | |||
