2002-10-10 · Major component of the axial/lateral elements of synaptonemal complexes (SCS) during meiotic prophase. Plays a role in the assembly of synaptonemal complexes. Required for normal meiotic chromosome synapsis during oocyte and spermatocyte development and for normal male and female fertility. Required for insertion of SYCP3 into synaptonemal complexes.

A) late prophase of meiosis I B) during fertilization or fusion of gametes C) early anaphase of meiosis I D) mid-prophase of meiosis II E) late metaphase of meiosis II Answer: A Among these molecules, the proteins constituting the synaptonemal complex (SC), a proteinaceous structure that holds together homologous chromosomes, are worth investigating, because evidence that they are expressed in cancer but not in normal somatic cells is accumulating. 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 (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).

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.
