The meiosis-specific Hop2 protein of S. cerevisiae ensures synapsis between homologous chromosomes

Article Abstract:

The protein responsible for the interaction of homologous chromosome during genetic recombination in Saccharomyces cerevisiae meiosis has been identified as HOP2 which stands for homologous pairing. Yeasts with mutations in the hop2 gene exhibit similar rates of synaptonemal complex formation as the wild-type strain but the resulting synapsis frequently involves nonhomologous chromosomes.

Multisite phosphorylation and the countdown to S phase

Article Abstract:

This review examines the regulatory control mechanisms of the cell cycle dynamics with reference to S phase and M phase cell division. The cyclin (Clb)-cyclin-dependent kinases are phosphorylated on multiple sites, which block rereplication of chromosomes during a single round of cell division. Implications of the research to protein nanoprocessors is discussed.

Zip3 provides a link between recombination enzymes and synaptonemal complex proteins

Article Abstract:

Results show that the meiosis-specific zip3 protein promotes synapsis and interacts with gene products of meiotic recombination. Data suggest that Zip3 is a component of the recombination nodules and links synapsis initiation process to the meiotic recombination.
