Hdf1 is the yeast homologue of the mammalian 70 kDa subunit of Ku- protein,
which has DNA end-binding activity and is involved in DNA double-strand
break repair and V(D)J recombination. To examine whether Hdf1 is involved
in illegitimate recombination, we have measured the rate of deletion
mutation caused by illegitimate recombination on a plasmid in an hdf1
disruptant. The hdf1 mutation reduced the rate of deletion formation by
20-fold, while it did not affect mitotic and meiotic homologous
recombinations between two heteroalleles or homologous recombination
between direct repeats. Hence Hdf1 participates in illegitimate
recombination, but not in homologous recombination, in contrast to Rad52,
Rad50, Mre11 and Xrs2, which are involved in both homologous and
illegitimate recombination. The illegitimate recombination in the hdf1
disruptant took place between recombination sites that shared short regions
of homology (1-4 bp), as was observed in the wild-type. Based on the DNA
end-binding activity of Hdf1, we discuss models in which Hdf1 plays an
important role in the late step of illegitimate recombination.
