Target: | Apbb1 is an adapter protein that forms a transcriptionally active complex with the gamma-secretase-derived amyloid precursor protein (APP) intracellular domain.Apbb1 plays a central role in the response to DNA damage by translocating to the nucleus and inducing apoptosis. Apbb1 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. Apbb1 is 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.Apbb1 functions in association with TSHZ3, SET and HDAC factors as a transcriptional repressor, that inhibits the expression of CASP4. Apbb1 is associates with chromatin in a region surrounding the CASP4 transcriptional start site(s). |
