Conformational dynamics of the Hop1 HORMA domain reveal a common mechanism with the spindle checkpoint protein Mad2. [PDF]
The HORMA domain is a highly conserved protein-protein interaction module found in eukaryotic signaling proteins including the spindle assembly checkpoint protein Mad2 and the meiotic HORMAD proteins.

Hexavalents in spermatocytes of Robertsonian heterozygotes between Mus m. domesticus 2n 26 from the Vulcano and Lipari Islands (Aeolian Archipelago, Italy) [PDF]
The size and shape of the chromosomes, as well as the chromosomal domains that compose them, are determinants in the distribution and interaction between the bivalents within the nucleus of spermatocytes in prophase I of meiosis.

Evolutionary history of the mammalian synaptonemal complex [PDF]
The synaptonemal complex (SC), a key structure of meiosis that assembles during prophase I, has been initially described 60 years ago. Since then, the structure has been described in many sexually reproducing organisms. However, the SC protein components were characterized in only few model organisms.

Human disease locus discovery and mapping to molecular pathways through phylogenetic profiling
Genes with common profiles of the presence and absence in disparate genomes tend to function in the same pathway. By mapping all human genes into about 1000 clusters of genes with similar patterns of conservation across eukaryotic phylogeny, we ...

Meiotic sex chromosome cohesion and autosomal synapsis are supported by Esco2.
In mitotic cells, establishment of sister chromatid cohesion requires acetylation of the cohesin subunit SMC3 (acSMC3) by ESCO1 and/or ESCO2. Meiotic cohesin plays additional but poorly understood roles in the formation of chromosome axial elements (AEs)

Errors in chromosome segregation during oogenesis and early embryogenesis [PDF]
Errors in chromosome segregation occurring during human oogenesis and early embryogenesis are very common. Meiotic chromosome development during oogenesis is subdivided into three distinct phases.

A molecular model for self-assembly of the synaptonemal complex protein SYCE3
The synaptonemal complex (SC) is a supramolecular protein assembly that mediates homologous chromosome synapsis during meiosis. This zipper-like structure assembles in a continuous manner between homologous chromosome axes, enforcing a 100-nm separation ...

Application of advanced fluorescence microscopy to the structure of meiotic chromosomes [PDF]
Chromosomes undergoing meiosis are defined by a macromolecular protein assembly called the synaptonemal complex which holds homologs together and carries out important meiotic functions.

Principles of meiotic chromosome assembly revealed in S. cerevisiae [PDF]
During meiotic prophase, chromosomes organise into a series of chromatin loops emanating from a proteinaceous axis, but the mechanisms of assembly remain unclear.

Apoptosis in mouse fetal and neonatal oocytes during meiotic prophase one [PDF]
Background The vast majority of oocytes formed in the fetal ovary do not survive beyond birth. Possible reasons for their loss include the elimination of non-viable genetic constitutions arising through meiosis, however, the ...
