LZTS1（leucine zipper tumor suppressor 1），癌症关联基因，基因ID：11178，该基因编码一种在正常组织中广泛表达的肿瘤抑制蛋白在葡萄膜黑色素瘤中，这种蛋白在快速转移和转移的肿瘤细胞中表达沉默，但在缓慢转移或非转移的肿瘤细胞中表达正常该蛋白可能通过与cdk1/cyclinb1复合物相互作用在细胞周期调控中发挥作用。该基因位于染色体8p22区8p臂杂合性缺失（loh）是多种癌症的共同特征。[由RefSeq提供，2009年11月]This gene encodes a tumor suppressor protein that is ubiquitously expressed in normal tissues. In uveal melanomas， expression of this protein is silenced in rapidly metastasizing and metastatic tumor cells but has normal expression in slowly metastasizing or nonmetastasizing tumor cells. This protein may have a role in cell-cycle control by interacting with the Cdk1/cyclinB1 complex. This gene is located on chromosomal region 8p22. Loss of heterozygosity (LOH) in the 8p arm is a common characteristic of many types of cancer. [provided by RefSeq， Nov 2009]。
