The highly ordered central region of the synaptonemal complex (SC) in Blaps cribrosa has recently been studied by electron microscope tomography (EMT), and a simple three-dimensional model presented. Using the same experimental approach we have now compared the central region in Blaps with the central regions in Drosophila melanogaster and rat. In all three species, the SCs exhibit a central element (CE) flanked by two lateral elements (LEs). The central region between the two LEs is crossed by… Expand
The central region of the synaptonemal complex inBlaps cribrosa studied by electron microscope tomography
TLDR
It is proposed that a TF with the two associated short pillars represents the structural unit in the central region and is accomplished by linking adjacent pillars to each other into the well-defined three-dimensional organization of the CE. Expand
The central element of the synaptonemal complex in mice is organized as a bilayered junction structure
TLDR
A bilayered junction structure essential for organization of the synaptonemal complex is described, crucial for synapsis of homologous chromosomes and for chromosome segregation. Expand
A close-to-native structure of the synaptonemal complex
TLDR
A novel electron microscopy sample-preparation approach is developed where pachytene cells are isolated from mouse testis by FACS, followed by cryo-fixation andcryo-substitution to achieve visualization of a close-to-native structure of the synaptonemal complex, and a structure nucleating the central element of the SC is identified.

Quantitative basis of meiotic chromosome synapsis analyzed by electron tomography
TLDR
This work applied electron tomography (ET) and manual feature extraction to generate a quantitative 3D model of the murine SC and provides the basis for analyzing multiprotein complexes in their morphological context using ET. Expand
A molecular model for self-assembly of the synaptonemal complex protein SYCE3
TLDR
A novel self-assembly mechanism of the SC central element component SYCE3 is reported, identified through multi-angle light scattering and small-angle X-ray scattering experiments, that adopts a dimeric four-helical bundle structure that acts as the building block for concentration-dependent self- assembly into a series of discrete higher-order oligomers.

Molecular structure of human synaptonemal complex protein SYCE1
TLDR
The structure of human SYCE1 is reported through solution biophysical methods including multi-angle light scattering and small-angle X-ray scattering to achieve structural stability of the SC central element. Expand
Superresolution expansion microscopy reveals the three-dimensional organization of the Drosophila synaptonemal complex
TLDR
Strong evidence is found that the Drosophila SC comprises two visually distinct layers, perhaps suggesting that each layer connects one sister chromatid from each homologous chromosome, and it is speculated that each SC layer may connect two nonsister chromatids. Expand
Zip1-induced changes in synaptonemal complex structure and polycomplex assembly
The yeast Zip1 protein is a component of the synaptonemal complex (SC), which is an elaborate macromolecular structure found along the lengths of chromosomes during meiosis. Mutations that increaseExpand
Organization of the Synaptonemal Complex During Meiosis in Caenorhabditis elegans
TLDR
A model of how the SYP proteins link the homologous axes to provide the conserved structure and width of the SC in Caenorhabditis elegans is proposed. Expand
Structural analysis of the human SYCE2–TEX12 complex provides molecular insights into synaptonemal complex assembly
TLDR
The first biochemical and structural analysis of an SC protein component is provided and a structural basis for its function in SC assembly is proposed and can be combined with existing biological data in a model of chromosome synapsis driven by growth of SYCE2–TEX12 higher-order structures within the CE of the SC.
