Function

[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).^[1] ^[2] ^[3] ^[4] ^[5]

Publication Abstract from PubMed

The neuronal adaptor protein Fe65 is involved in brain development, Alzheimer disease amyloid precursor protein (APP) signaling, and proteolytic processing of APP. It contains three protein-protein interaction domains, one WW domain, and a unique tandem array of phosphotyrosine-binding (PTB) domains. The N-terminal PTB domain (Fe65-PTB1) was shown to interact with a variety of proteins, including the low density lipoprotein receptor-related protein (LRP-1), the ApoEr2 receptor, and the histone acetyltransferase Tip60. We have determined the crystal structures of human Fe65-PTB1 in its apo- and in a phosphate-bound form at 2.2 and 2.7A resolution, respectively. The overall fold shows a PTB-typical pleckstrin homology domain superfold. Although Fe65-PTB1 has been classified on an evolutionary basis as a Dab-like PTB domain, it contains attributes of other PTB domain subfamilies. The phosphotyrosine-binding pocket resembles IRS-like PTB domains, and the bound phosphate occupies the binding site of the phosphotyrosine (Tyr(P)) within the canonical NPXpY recognition motif. In addition Fe65-PTB1 contains a loop insertion between helix alpha2 and strand beta2(alpha2/beta2 loop) similar to members of the Shc-like PTB domain subfamily. The structural comparison with the Dab1-PTB domain reveals a putative phospholipid-binding site opposite the peptide binding pocket. We suggest Fe65-PTB1 to interact with its target proteins involved in translocation and signaling of APP in a phosphorylation-dependent manner.
