== Function ==
 
[https://www.uniprot.org/uniprot/APBB1_HUMAN APBB1_HUMAN] Transcription coregulator that can have both coactivator and corepressor functions. Adapter protein that forms a transcriptionally active complex with the gamma-secretase-derived amyloid precursor protein (APP) intracellular domain. 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. Function in association with TSHZ3, SET and HDAC factors as a transcriptional repressor, that inhibits the expression of CASP4. Associates with chromatin in a region surrounding the CASP4 transcriptional start site(s).<ref>PMID:15031292</ref> <ref>PMID:18468999</ref> <ref>PMID:18922798</ref> <ref>PMID:19234442</ref> <ref>PMID:19343227</ref>

Fe65 is a three-domain neuronal adaptor protein involved in brain development and amyloid precursor protein (APP) signalling. The phosphotyrosine-binding domain 1 (PTB1) of human Fe65 has been cloned, overexpressed, purified and crystallized using the hanging-drop vapour-diffusion method. Native crystals belong to the space group R3 and diffract to 2.6 A resolution. This crystal form suffered from high thermal B factors and pseudo-symmetry, resulting in a bisection of the c axis. Co-crystallization with a mercury compound under similar conditions induced an orthorhombic crystal form in the space group P2(1)2(1)2(1) diffracting to 2.2 A resolution. SAD phases have been computed to the diffraction limit at the wavelength of maximum absorption (L(III) edge).
