SMARCD1（SWI/SNF related， matrix associated， actin dependent regulator of chromatin， subfamily d， member 1），癌症关联基因，基因ID：6602，该基因编码的蛋白质是SWI / SNF蛋白质家族的成员，其成员具有解旋酶和ATPase活性，被认为可以通过改变那些基因周围的染色质结构来调节某些基因的转录。 编码的蛋白质是大型ATP依赖的染色质重塑复合体SNF / SWI的一部分，并且与酵母Swp73蛋白具有序列相似性。 已经发现该基因的两个编码不同同工型的转录物变体。 [由RefSeq提供，2008年7月]The protein encoded by this gene is a member of the SWI/SNF family of proteins， whose members display helicase and ATPase activities and which are thought to regulate transcription of certain genes by altering the chromatin structure around those genes. The encoded protein is part of the large ATP-dependent chromatin remodeling complex SNF/SWI and has sequence similarity to the yeast Swp73 protein. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq， Jul 2008]。
