摘　　要：CDY(chromodomain protein,Y-linked)基因位于Y染色体AZF区段,是Y染色体微缺失所导致的生精障碍的候选基因之一。CDY基因起源于常染色体CDYLs(CDY-like)基因m RNA的反转录转座。在进化过程中,CDYLs基因家族通过增加新的外显子从而获得蛋白功能的多样性。CDYLs/CDY蛋白包含2个重要的结构域:氨基端的chromo结构域可结合甲基化的组蛋白,主要参与基因沉默的过程;羧基端的crotonase结构域可能参与组蛋白乙酰化的催化,可能在精子发生中发挥重要作用。综述CDYLs/CDY基因的进化、功能及其临床意义。As located in AZF region of Y chromosome,CDY（chromodomain protein,Y-linked） gene has been regarded as one of the candidates of Y chromosome microdeletion related to dyszoospermia. Actually,CDY gene originated from the reverse transcription and transposition of autosomal CDYLs（CDY-like） m RNA. During the evolution,autosomal CDYLs acquired the diversity of protein function by acquisition of new exons. The function of CDYLs/CDY protein closely depends on its two domains,the chromo domain mediating the gene silence process by binding to the methylated histones and the crotonase domain which might be involved in spermatogenesis via its histone acetylase activity. Herein,the research progress about the CDYLs/CDY gene family was reviewed.
