Heterogeneity in conservation of multifunctional partner enzymes with meiotic importance, CDK2 kinase and BRCA1 ubiquitin ligase [PDF]
The evolution of proteins can be accompanied by changes not only to their amino acid sequences, but also their structural and spatial molecular organization.

Crystal Structure of C-Terminal Coiled-Coil Domain of SYCP1 Reveals Non-Canonical Anti-Parallel Dimeric Structure of Transverse Filament at the Synaptonemal Complex. [PDF]
The synaptonemal complex protein 1 (SYCP1) is the main structural element of transverse filaments (TFs) of the synaptonemal complex (SC), which is a meiosis-specific complex structure formed at the synapse of homologue chromosomes to hold them together ...

Coiled-coil structure of meiosis protein TEX12 and conformational regulation by its C-terminal tip
The X-ray crystal structures of C-terminal mutants of the coiled-coil protein cancer testis antigen TEX12 in combination with modeling of the TEX12 wild-type dimer reveal the protein’s control of its oligomeric state, which resembles assembly of its ...

Ipl1/aurora kinase suppresses S-CDK-driven spindle formation during prophase I to ensure chromosome integrity during meiosis [PDF]
Cells coordinate spindle formation with DNA repair and morphological modifications to chromosomes prior to their segregation to prevent cell division with damaged chromosomes.

The tumor suppressor BRCA1-BARD1 complex localizes to the synaptonemal complex and regulates recombination under meiotic dysfunction in Caenorhabditis elegans. [PDF]
Breast cancer susceptibility gene 1 (BRCA1) and binding partner BRCA1-associated RING domain protein 1 (BARD1) form an essential E3 ubiquitin ligase important for DNA damage repair and homologous recombination. The Caenorhabditis elegans orthologs, BRC-1

A conserved filamentous assembly underlies the structure of the meiotic chromosome axis. [PDF]
The meiotic chromosome axis plays key roles in meiotic chromosome organization and recombination, yet the underlying protein components of this structure are highly diverged.

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.

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
