Fragments of Fen1 that interact with PCNA are disclosed, together with the use of such fragments or mimetics of Fen1 in methods of screening for compounds useful in treating disorders in which PCNA is implicated. In particular, substances which have the property of binding to PCNA are disclosed, said substances comprising:(i) a fragment of the Fen1 protein containing a peptide of 89 amino acids from the C-terminal region or an active portion thereof; or,(ii) a fragment of the Fen1 protein containing the sequence motif QGRLDxFF; or,(iii) a functional mimetic of said protein fragments;where "x" is preferably the selected form the amino acids S, D or G. |
