The high affinity DNA binding factor (HDF) protein of Saccharomyces cerevisiae is composed of two subunits and specifically binds ends of double-stranded DNA. The 70-kDa subunit, HDF1, shows significant homology with the 70-kDa subunit of the human Ku protein. Like the Ku protein, HDF1 has been shown to be involved in recombination and double stranded DNA(More)
Kinesin-1 dimerizes via the coiled-coil neck domain. In contrast to animal kinesins, neck dimerization of the fungal kinesin-1 NcKin requires additional residues from the hinge. Using chimeric constructs containing or lacking fungal-specific elements, the proximal part of the hinge was shown to stabilize the neck coiled-coil conformation in a complex(More)
Two roles for the Saccharomyces cerevisiae Cdc13 protein at the telomere have previously been characterized: it recruits telomerase to the telomere and protects chromosome ends from degradation. In a synthetic lethality screen with YKU70, the 70-kDa subunit of the telomere-associated Yku heterodimer, we identified a new mutation in CDC13, cdc13-4, that(More)
The Yku heterodimer from Saccharomyces cerevisiae, comprising Yku70p and Yku80p, is involved in the maintenance of a normal telomeric DNA end structure and is an essential component of nonhomologous end joining (NHEJ). To investigate the role of the Yku70p subunit in these two different pathways, we generated C-terminal deletions of the Yku70 protein and(More)
