ZMAT3（zinc finger matrin-type 3），癌症关联基因，基因ID：64393，这个基因编码一个含有三个锌指结构域和一个核定位信号的蛋白质。该基因的mRNA和蛋白被野生型p53上调，过度表达抑制肿瘤细胞生长，提示该基因可能参与p53依赖性生长调控途径这个基因的选择性剪接导致两个转录变体编码两个只有一个氨基酸不同的亚型。[由RefSeq提供，2008年7月]This gene encodes a protein containing three zinc finger domains and a nuclear localization signal. The mRNA and the protein of this gene are upregulated by wildtype p53 and overexpression of this gene inhibits tumor cell growth， suggesting that this gene may have a role in the p53-dependent growth regulatory pathway. Alternative splicing of this gene results in two transcript variants encoding two isoforms differing in only one amino acid. [provided by RefSeq， Jul 2008]。
