CHD蛋白家族的特征是存在染色質組織修飾域和SNF2相關的螺旋酶/ATPase結構域chd基因可能通過改變染色質結構來改變基因表達，從而改變轉錄設備對其染色體dna模板的訪問。[由RefSeq提供，2008年7月]
The CHD family of proteins is characterized by the presence of chromo (chromatin organization modifier) domains and SNF2-related helicase/ATPase domains. CHD genes alter gene expression possibly by modification of chromatin structure thus altering access of the transcriptional apparatus to its chromosomal DNA template. [provided by RefSeq, Jul 2008]
