| 中文摘要: |
| 摘要：异染色质是指在细胞周期中维持凝缩状态的染色质，具有维持染色体稳定性和调节真核细胞基因表达的作用。异染色质相关蛋白1(heterochromatin associated protein1，HP1)是异染色质的特征性蛋白，进化高度保守，在哺乳动物有三种亚型：HP1α、HP1β和HP1γ(分别由CBX5、CBX1和CBX3基因编码)，在哺乳动物配子发生、受精、胚胎的着床及胚胎发育过程中都有着自己独特的作用，本文主要对HP1的各个亚型在哺乳动物生殖过程中的作用及其异常对生殖过程的影响作一综述。 |

| ABSTRACT: Heterochromatin is the chromatin that maintains condensed in the cell cycle, which can maintain the chromosome stability and regulate the expression of eukaryotic gene. Heterochromatin associated protein 1 (HP1) is characteristic of heterochromatin protein, whose evolution is highly conserved. There are three subtypes: HP1α, HP1β and HP1γ in mammals (three proteins are encoded as CBX5, CBX1and CBX3 respectively). HP1s has unique role in the gametogenesis, fertilization, embryonic development and embryo implantation. In this paper, we review the role of three subtypes during mammal reproductive process. |
