“…To define association of these proteins with meiotic chromosomes, spread nuclei were doublestained with antibodies to the myc epitope and to Zip1, the protein that makes up the transverse filaments of the synaptonemal complex (SC) (Sym et al 1993). The stage in meiotic prophase can be determined for any given nucleus based on the extent of SC formation (Fig.…”

In most sexually reproducing organisms, meiotic recombination is initiated by DNA double-strand breaks (DSBs) formed by the Spo11 protein. In budding yeast, nine other proteins are also required for DSB formation, but roles of these proteins and interactions among them are poorly understood. We report here further studies of the behaviors of these proteins. Consistent with other studies, we find that Mei4 and Rec114 bind to chromosomes from leptonema through early pachynema. Both proteins showed only limited colocalization with the meiotic cohesin subunit Rec8, suggesting that Mei4 and Rec114 associated preferentially with chromatin loops. Rec114 localization was independent of other DSB factors, but Mei4 localization was strongly dependent on Rec114 and Mer2. Systematic deletion analysis identified protein regions important for a previously described two-hybrid interaction between Mei4 and Rec114. We also report functional characterization of a previously misannotated 5′ coding exon of REC102. Sequences encoded in this exon are essential for DSB formation and for Rec102 interaction with Rec104, Spo11, Rec114, and Mei4. Finally, we also examined genetic requirements for a set of previously described two-hybrid interactions that can be detected only when the reporter strain is induced to enter meiosis. This analysis reveals new functional dependencies for interactions among the DSB proteins. Taken together, these studies support the view that Mei4, Rec114, and Mer2 make up a functional subgroup that is distinct from other subgroups of the DSB proteins: Spo11-Ski8, Rec102-Rec104, and Mre11-Rad50-Xrs2. These studies also suggest that an essential function of Rec102 and Rec104 is to connect Mei4 and Rec114 to Spo11.

“…TF proteins, have therefore been identified independently in only a limited number of species, namely mammalian species (SYCP1) (Meuwissen et al, 1992), budding yeast (Zip1) (Sym et al, 1993), Drosophila (C(3)G) (Page and Hawley, 2001) and Caenorhabditis (Syp-1 and Syp-2) (Colaia´covo et al, 2003;MacQueen et al, 2002). Despite their lack of amino acid sequence similarity, SYCP1, Zip1 and C(3)G have a similar structure: they are long coiled coil proteins with globular domains at both ends.…”

“…In Caenorhabditis and Drosophila meiotic crossing over is completely abolished (Colaia´covo et al, 2003;MacQueen et al, 2002;Page and Hawley, 2001), and in mouse almost completely (de Vries et al, 2005). Yeast zip1 null mutants on the other hand, still display about 30% of the wildtype level of crossing over (Sym et al, 1993).…”

Meiosis is a specialized set of two nuclear divisions, meiosis I and II, by which a diploid cell produces four haploid daughters. After premeiotic DNA replication, homologous chromosomes pair and recombine, and then disjoin at meiosis I. Subsequently, at meiosis II, the sister chromatids of each chromosome segregate. In nearly all eukaryotes, meiotic chromosome pairing culminates in the formation of a ladderlike supramolecular protein structure, the synaptonemal complex (SC) (Page and Hawley, 2004). The rungs of the ladder are known as transverse filaments (TFs). Genes encoding TF proteins have been identified in a limited number of organisms, and their function has been studied by mutational analysis. Although TF proteins show little amino acid sequence conservation, their structure and function are largely conserved. In all analyzed species, TF proteins are required for meiotic reciprocal recombination (crossing over).
