C14ORF39/SIX6OS1 is a constituent of the synaptonemal complex and is essential for mouse fertility

Nature Communications, 2016
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

G3: Genes, Genomes, Genetics, 2023
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.

A BIRD´S-EYE VIEW OF CHROMOSOMES DURING MEIOTIC PROPHASE I [PDF]

BAG. Journal of Basic and Applied Genetics, 2022
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

Principles of meiotic chromosome assembly revealed in S. cerevisiae [PDF]

, 2019
During meiotic prophase, chromosomes organise into a series of chromatin loops emanating from a proteinaceous axis, but the mechanisms of assembly remain unclear.

Sycp2 is essential for synaptonemal complex assembly, early meiotic recombination and homologous pairing in zebrafish spermatocytes.

PLoS Genetics, 2020
Meiotic recombination is essential for faithful segregation of homologous chromosomes during gametogenesis. The progression of recombination is associated with dynamic changes in meiotic chromatin structures.

Hexavalents in spermatocytes of Robertsonian heterozygotes between Mus m. domesticus 2n 26 from the Vulcano and Lipari Islands (Aeolian Archipelago, Italy) [PDF]

, 2018
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.

Meiotic sex chromosome cohesion and autosomal synapsis are supported by Esco2.

, 2020
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)

Evidence that MEK1 positively promotes interhomologue double-strand break repair [PDF]

, 2010
During meiosis there is an imperative to create sufficient crossovers for homologue segregation. This can be achieved during repair of programmed DNA double-strand breaks (DSBs), which are biased towards using a homologue rather than sister chromatid as ...

Meiosis in mice without a synaptonemal complex.

PLoS ONE, 2011
The synaptonemal complex (SC) promotes fusion of the homologous chromosomes (synapsis) and crossover recombination events during meiosis. The SC displays an extensive structural conservation between species; however, a few organisms lack SC and execute ...
