联会复合体(synaptonemal complex,SC)是同源染色体之间具有三级结构的阶梯状聚合亚蛋白复合体,大部分由减数分裂特异性蛋白组成,联会复合体的装配开始于第一次减数分裂前期早期。在细线期,被命名为轴成分(axial elements,AEs)的蛋白沿染色体轴形成;在偶线期,配对的同源染色体的AEs,现在称作为侧向原件(lateral elements,LEs),按同源染色
The synaptonemal complex (SC) is a ladder-like polymeric subprotein complex with tertiary structure between homologous chromosomes, most of which is composed of meiosis-specific proteins. Assembly of the synaptonemal complex begins at the first Submucosal early prophase. At the thin line, proteins named axial elements (AEs) are formed along the axis of the chromosome; at the even line, the AEs of paired homologous chromosomes, now referred to as lateral elements (LEs) Homologous staining
