SMARCAD1 is a SWI/SNF-like chromatin remodeling protein that plays a critical role in the maintenance of heterochromatin domains following DNA replication and proper chromosome segregation during mitosis (1-3). SMARCAD1 can be found in association with transcription repressor KAP1, histone deacetylases HDAC1/2, and lysine methyltransferase G9a/GLP, which are recruited to sites of DNA replication by PCNA. These proteins facilitate deacetylation of histones and methylation of histone H3 Lys9 to re-establish heterochromatin domains, such as centromeric regions (1). SMARCAD1 also plays a role in double stranded DNA break repair by facilitating DNA end resection and the subsequent repair by homologous recombination (4). Loss of SMARCAD1 results in increased sensitivity to DNA damaging agents, suggesting a role in the maintenance of genome stability.

SMARCAD1是一个SWI/SNF样染色质重塑蛋白,对于DNA复制之后异染色质结构域的维持以及有丝分裂期间染色体的正确分离有至关重要的作用(1-3)。经研究发现SMARCAD1与转录阻遏子 KAP1,组蛋白去乙酰化酶HDAC1/2以及赖氨酸甲基转移酶G9a/GLP联系在一起,这些都会被PCNA募集到DNA复制位点上。这些蛋白能够有助于组蛋白的去乙酰化以及组蛋白H3 Lys9位点的甲基化从而建立一个异染色质结构域,如着丝粒区(1)。SMARCAD1还可以促进DNA末端切除和随后的同源重组的修复,对于双链DNA断裂修饰是很重要(4)。SMARCAD1确实会导致提高对DNA损伤事件的敏感度,这意味着其在基因组稳定性维持的重要作用。
