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

What is the synaptonemal complex? 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 protein 3 is a marker for cell transformation that has prognostic significance in various cancers.

Synaptonemal complex

Definition of synaptonemal complex. : a complex tripartite protein structure that spans the region between synapsed chromosomes in meiotic prophase.

Synaptonemal complex

File history. 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). Description The synaptonemal complex (SC) is a highly ordered proteinaceous structure that assembles at the interface between aligned homologous chromosomes during meiotic prophase. The SC has been demonstrated to function both in stabilization of homolog pairing and in promoting the formation of interhomolog crossovers (COs).

Synaptonemal complex

Plays a lesser role in female fertility. 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. 2002-10-10 · Major component of the axial/lateral elements of synaptonemal complexes (SCS) during meiotic prophase.
