Fraune J, Schramm S, Alsheimer M, Benavente R (2012) The mammalian synaptonemal complex: protein components, assembly and role in meiotic recombination. Exp Cell Res 318:1340–1346 CAS Article PubMed Google Scholar 2020-02-24 · Here, we describe that Sycp2 is required for assembly of the synaptonemal complex and early meiotic events in zebrafish spermatocytes. Our genetic screening by N-ethyl-N-nitrosourea mutagenesis revealed that ietsugu ( its ), a mutant zebrafish line with an aberrant splice site in the sycp2 gene, showed a defect during meiotic prophase I. The synaptonemal complex transiently stabilizes pairing interactions between homologous chromosomes during meiosis.

Synaptonemal complex

Abstract.

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. The synaptonemal complex is a tripartite structure consisting of two parallel lateral regions and a central element.
