Conrad MN, et al. (1997) Ndj1p, a meiotic telomere protein required for normal chromosome synapsis and segregation in yeast. Science 276(5316):1252-5
Abstract: The Saccharomyces cerevisiae gene NDJ1 (nondisjunction) encodes a protein that accumulates at telomeres during meiotic prophase. Deletion of NDJ1 (ndj1Delta) caused nondisjunction, impaired distributive segregation of linear chromosomes, and disordered the distribution of telomeric Rap1p, but it did not affect distributive segregation of circular plasmids. Induction of meiotic recombination and the extent of crossing-over were largely normal in ndj1Delta cells, but formation of axial elements and synapsis were delayed. Thus, Ndj1p may stabilize homologous DNA interactions at telomeres, and possibly at other sites, and it is required for a telomere activity in distributive segregation.
