HDF2, L000004089, YMR106C
Subunit of the telomeric Ku complex (Yku70p-Yku80p); involved in telomere length maintenance, structure and telomere position effect; required for localization of telomerase ribonucleoprotein via interaction with the TLC1 guide RNA; relocates to sites of double-strand cleavage to promote nonhomologous end joining during DSB repair

Dosage Lethality

A genetic interaction is inferred when over expression or increased dosage of one gene causes lethality in a strain that is mutated or deleted for another gene.

The Est3 protein associates with yeast telomerase through an OB-fold domain.

Lee J, Mandell EK, Tucey TM, Morris DK, Lundblad V

The Ever shorter telomeres 3 (Est3) protein is a small regulatory subunit of yeast telomerase which is dispensable for enzyme catalysis but essential for telomere replication in vivo. Using structure prediction combined with in vivo characterization, we show here that Est3 consists of a predicted OB (oligosaccharide/oligonucleotide binding)-fold. We used mutagenesis of predicted surface residues to generate a functional map ... [more]
