Fred grew up in California and studied biology and played the violin at Princeton as an undergraduate. He obtained an M.D. Ph.D. at UCSF, studying under the wise tutelage of the late Ira Herskowitz. As a graduate student, he played with budding yeast ‘shmoos’ and studied how yeast pheromones arrest the cell cycle. He then went to do postdoctoral stints with Paul Nurse in Oxford and London, and ...

In the budding yeast Saccharomyces cerevisiae the Srs2/RadH DNA helicase promotes survival after ultraviolet (UV) irradiation, and has been implicated in DNA repair, recombination and checkpoint signalling following DNA damage. A second helicase, Sgs1, is the S.cerevisiae homologue of the human BLM and WRN proteins, which are defective in cancer predisposition and/or premature ageing syndromes....

ABSTRACT First Person is a series of interviews with the first authors selection papers published in Journal Cell Science, helping researchers promote themselves alongside their papers. Kerstin Hinterndorfer and Felix Mikus are co-first on ‘ Ultrastructure expansion microscopy reveals cellular architecture budding fission yeast’, JCS. PhD student lab Robbie Loewith at University Geneva, Switzer...

Microtubule-organizing centers such as the γ-tubulin ring complex (γ-TuRC) act as a template for polarized growth and regulation of microtubules that are essential for diverse cellular structures and processes in eukaryotes. New structural models of the budding yeast γ-tubulin small complex (γ-TuSC) of the γ-TuRC combined with functional studies done in multiple eukaryotes are revealing the fir...

Ars3002 is an efficient single-copy replication origin in the fission yeast, Schizosaccharomyces pombe. In a previous study, we tested the effects of consecutive approximately 50-bp deletions throughout ars3002 on the replication efficiency of those origins in S. pombe. Here we report the results of our use of the same approximately 50-bp deletions to test the hypothesis that some of the cis-ac...

hda1+ (histone deacetylase 1) is a fission yeast gene which is highly similar in sequence to known histone deacetylase genes in humans and budding yeast. We have investigated if this putative histone deacetylase contributes to transcriptional silencing in the fission yeast Schizosaccharomyces pombe. A precise deletion allele of the hda1+ open reading frame was created. Cells lacking the hda1+ g...

The eukaryotic intra-S-phase checkpoint, which slows DNA synthesis in response to DNA damage, is poorly understood. Is DNA damage recognized directly, or indirectly through its effects on replication forks? Is the slowing of S phase in part because of competition between DNA synthesis and recombination/repair processes? The results of our genetic analyses of the intra-S-phase checkpoint in the ...
