These data suggested that the centrin isoforms played different roles in different stages of spermatogenesis. The centrin-1 gene was revealed to be relevant to the centriolar translocation to the posterior pole of cell and the elaboration of flagellum during spermiogenesis, while the centrin-2 and centrin-3 might play roles in spermatogonial mitosis but were not involved in the spermatid differentiation process.
这些结果提示,Centrin同源基因在精子发生的不同阶段发挥不同功能,其中Centrin-1与精子细胞分化期的中心体后移、鞭毛的生成及精子中轴形成可能密切相关,Centrin-2和-3则可能在精原细胞有丝分裂中起作用,而与精子细胞变态分化无关。
