'''NMR STRUCTURE OF A NEW PHOSPHOTYROSINE BINDING DOMAIN CONTAINING THE FHA2 DOMAIN OF RAD 53'''
===NMR STRUCTURE OF A NEW PHOSPHOTYROSINE BINDING DOMAIN CONTAINING THE FHA2 DOMAIN OF RAD 53===




==Overview==
<!--
The forkhead-associated (FHA) domain is a 55-75 amino acid residue module found in &gt;20 proteins from yeast to human. It has been suggested to participate in signal transduction pathways, perhaps via protein-protein interactions involving recognition of phosphopeptides. Neither the structure nor the ligand of FHA is known. Yeast Rad53, a checkpoint protein involved in DNA damage response, contains two FHA domains, FHA1 (residues 66-116) and FHA2 (residues 601-664), the second of which recognizes phosphorylated Rad9. We herein report the solution structure of an "FHA2-containing domain" of Rad53 (residues 573-730). The structure consists of a beta-sandwich containing two antiparallel beta-sheets and a short, C-terminal alpha-helix. Binding experiments suggested that the FHA2-containing domain specifically recognizes pTyr and a pTyr-containing peptide from Rad9, and that the binding site involves residues highly conserved across FHA domains. The results, along with other recent reports, suggest that FHA domains could have pTyr and pSer/Thr dual specificity.
