POZ锌指蛋白在发育和肿瘤发生中的作用

Roles of POZ-ZF Proteins in Development and Oncogenesis

POZ锌指蛋白是一类在进化中高度保守的蛋白,具有多种重要的生物学功能。POZ锌指蛋白主要作为一种转录抑制因子而存在,通过POZ结构域招募一些转录辅阻遏物而调节靶基因的表达。近年来的研究发现,POZ锌指蛋白在发育和肿瘤的发生中有着重要的作用,综述5个POZ锌指蛋白在肿瘤的发生和生物体发育中的作用及功能,为人们进一步了解POZ锌指蛋白的功能提供资料。

POZ-ZF proteins are highly conserved proteins implicated many biological processes in invertebrate and vertebrate. Members of the POZ-ZF protein contain an amino-terminal POZ domain and a carboxy-terminal DNA-binding domain made of one or more zinc finger motifs and usually act as transcriptional co-repressors to regulate target genes expression. Recent studies showed that POZ-ZF proteins play important roles in development and oncogenesis. In this review, we summarize studies of five POZ-ZF proteins, which is helpful to further understand POZ-ZF proteins.
