多形性腺瘤基因1编码锌指蛋白和2个假定的核定位信号。plag1是一种发育调控因子，在涎腺多形性腺瘤中被一致地重新排列。plag1被唾液腺多形性腺瘤中涉及8q12的相互染色体易位激活。已经发现了三个编码两种不同亚型的转录变体[由RefSeq提供，2008年7月]
Pleomorphic adenoma gene 1 encodes a zinc finger protein with 2 putative nuclear localization signals. PLAG1, which is developmentally regulated, has been shown to be consistently rearranged in pleomorphic adenomas of the salivary glands. PLAG1 is activated by the reciprocal chromosomal translocations involving 8q12 in a subset of salivary gland pleomorphic adenomas. Three transcript variants encoding two different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]
