Phosphopeptide sequences of FHA domain–peptide complexes.

Sequences forming a secondary structure, α helix and β sheet, are in bold italic and italic format, respectively. Bold highlights the primary phosphothreonine binding residue. †and * represent peptides from library screening and biological study, respectively.形成二级结构的序列中，α螺旋（α helix）和β折叠（β sheet）分别采用粗斜体和斜体格式标注。粗体用于突出显示主要的磷酸苏氨酸（phosphothreonine）结合残基。符号†和*分别代表来自文库筛选和生物学研究的肽段。
