C14ORF39/SIX6OS1 is a constituent of the synaptonemal complex and is essential for mouse fertility
The synaptonemal complex is a meiosis-specific proteinaceous structure that supports homologous chromosome pairs during meiosis. Here, the authors show that SIX6OS1 (of previously unknown function) is part of the synaptonemal complex central element and ...

A molecular cell biology toolkit for the study of meiosis in the silkworm Bombyx mori
Meiosis is usually described as 4 essential and sequential processes: (1) homolog pairing; (2) synapsis, mediated by the synaptonemal complex; (3) crossing over; and (4) segregation.

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.

A BIRD´S-EYE VIEW OF CHROMOSOMES DURING MEIOTIC PROPHASE I [PDF]
The present review aims to summarize the research carried out in relation to meiosis in birds, especially by observing the protein axes of the chromosomes in prophase I of meiosis. This line of research, initially developed in Argentina, has provided key

Oriented Getzler-Kapranov complexes and framed curves [PDF]
In the present paper, we introduce and study oriented Getzler-Kapranov complexes. These complexes are generalizations of S. Merkulov's oriented graph complex. We investigate their relation to the cohomology of moduli spaces of complex and tropical curves, ribbon graph complexes, and motivic structures in string topology.

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 ...

Surveillance of cohesin-supported chromosome structure controls meiotic progression
Meiosis-specific cohesins and the synaptonemal complex are essential for meiotic chromosome structure and function. Here the authors show that continued surveillance of these chromosome structures controls meiotic progression by regulating CHK-2, a ...

During meiosis, homologous chromosomes undergo a dramatic movement in order to correctly align. This is a critical meiotic event but the molecular properties of this ‘chromosomal dance’ still remainunclear.

Relating CAT(0) cubical complexes and flag simplicial complexes [PDF]
Given a finite CAT(0) cubical complex, we define a flag simplicial complex associated to it, called the crossing complex. We show that the crossing complex holds much of the combinatorial information of the original cubical complex: for example, hyperplanes in the cubical complex correspond to vertex links in the crossing complex, and the crossing ...
