The synaptonemal complex (SC) is a meiosis-specific multiprotein complex that forms between homologous chromosomes during prophase of meiosis I. Once assembled, the SC mediates and maintains synapsis along the full length of each pair of homologous chromosomes. The major functions of Synaptonemal complex 1. Maintenance of synapsis in fixed state for an extended period for crossing over to occur. 2. To provide a structural framework within which exchange of segments takes place. 3. To segregate recombination DNA from the rest of other chromosomal DNA. Here, we show that the synaptonemal complex, a structure that zips homologous chromosomes together during meiosis, is essential for crossover interference in Arabidopsis .

Synaptonemal complexes (SCs) are zipper-like structures which are assembled between homologous chromosomes during the prophase of the first meiotic division.

Als synaptonemaler Komplex, seltener auch synaptischer Komplex, wird in der Zellbiologie eine Struktur aus Proteinen, RNA und DNA bezeichnet, die während einer bestimmten Phase der Meiose im Zellkern vorliegt und bei der Paarung von Chromosomen eine Rolle spielt. Synaptonemal complex protein 3 is a marker for cell transformation that has prognostic significance in various cancers.

What is the synaptonemal complex?

The synaptonemal complex was first visualized by Moses and Fawcett in 1956.107,108 As a complete tripartite protein structure, it consists of two lateral elements that align each homolog and the central element. Synaptonemal complex (SC) was first reported in both vertebrates and invertebrates by Fawcett and Moses in 1956. Its position within the bivalent was initially detected by the reconstruction of serial sections under electron microscopy (EM).

The TF of the SC has been shown to be required for class I CO formation in species as diverse as budding yeast, mice, S. Macrospora, Drosophila, … 2006-10-01 Sometimes synaptonemal complex like structures are also found which are not associated with synapsed chromosomes. They show some similarities with the true synaptonemal complex.

The lateral elements of these anomalous complexes may differ in size and density from those in the true synaptonemal complexes of that species. synaptonemal complex A ribbon-like complex of proteins that binds together the members of each homologous pair of chromosomes during pairing (synapsis) in prophase of the first division of meiosis.Formation of the complex begins at the telomeres, which at this stage are attached to the nuclear envelope, and proceeds along the length of the chromosomes, ‘zipping’ them together so that When does the synaptonemal complex disappear?
