It is formed during the ZYGOTENE STAGE of the first meiotic division. It is a prerequisite for CROSSING OVER. Schematic of the synaptonemal complex at different stages during Prophase I. Items portrayed in this file depicts.

Synaptonemal complex: A protein structure that forms between two homologous chromosomes during meiosis and that is thought to mediate chromosome pairing, synapsis, and recombination. The synaptonemal complex is a tripartite structure consisting of two parallel lateral regions and a central element.

The synaptonemal complex is a tripartite structure consisting of two parallel lateral regions and a central element. 2002-10-10 · Major component of the axial/lateral elements of synaptonemal complexes (SCS) during meiotic prophase.

synaptonemaalinen kompleksi. Finnish We have therefore studied telomere dynamics by FISH and synapsis formation by immunostaining of synaptonemal complex proteins (SCP3, SCP1) on ovarian Wapl localization on the synaptonemal complex, a meiosis-specific proteinaceous structure that binds homologous chromosomes, in the female mouse. Wapl, localized on the synaptonemal complex in female meiotic chromosomes and known to be affected by for example dioxin and 3-methylcholanthrene, has prophase of meiosis I, most important being homologous chromosome pairing, meiotic recombination and formation of the synaptonemal complex (SC).

1 Composition 2 Assembly and Disassembly 3 Necessity in Eukaryotes 4 External links 5 References The synaptonemal complex (SC) is a protein structure that forms between homologous chromosomes (two pairs of sister chromatids) during meiosis and is thought to mediate synapsis and recombination during meiosis I in eukaryotes. It is currently thought that the SC functions primarily as a scaffold 2002-10-10 Description The synaptonemal complex (SC) is a proteinaceous structure that is transiently formed during meiosis to promote homologous recombination between maternal and paternal chromosomes. syn·ap·ti·ne·mal complex also syn·ap·to·ne·mal complex (sĭ-năp′tə-nĕm′əl) The synaptonemal complex is a prominent, evolutionarily conserved feature of meiotic prophase. The assembly of this structure is closely linked to meiotic recombination. A recent study in budding yeast reveals an unexpected role in centromere pairing for a protein component of the synaptonemal complex, Zip1.

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.

It is a 0.2uM thick protein rich frame work. These lateral lines are flanked by chromatin. The two lateral lines are denser than the central line. Each lateral line is attached to the inner side of the homologous chromosome. 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. Synaptonemal complex: A protein structure that forms between two homologous chromosomes during meiosis and that is thought to mediate chromosome pairing, synapsis, and recombination.
