... further our knowledge withrespect to the mechanisms of action of these proteins,it is crucial that we define the precise boundaries of the STI1-homologous domain and compare the struc-tures of ... phosphoprotein STI1. We determined the solution structure of a protein fragment containing amino acids 275–342 of hHR23B (termedXPCB–hHR23B) and compared it with the previously reported solution structures ...
