摘要: 摘要MLN64基因定位于17号染色体的q12-q21区,编码的MLN64蛋白为一含445个氨基酸残基的跨膜蛋白。MLN64蛋白的C端域与StAR蛋白有高度同源性,N端域可使MLN64蛋白定位于次级内体膜上。MLN64蛋白参与胆固醇的转运和类固醇激素的合成。MLN64,与C-erbB-2基因相似,在乳腺癌中呈过表达,可以影响乳腺癌细胞的生物学特点。研究表明MLN64的高表达可能通过增加肿瘤内的类固醇激素合成促进乳腺癌的生长和进展,也被认为是乳腺癌预后的一个预测因子。

Abstract: AbstractThe MLN64 gene, which is localized in q12-q21 of the human chromosome 17, encodes a novel transmembrane protein containing 445 amino acids. The C-terminus of MLN64 shares significant homology with the steroidogenic acute regulatory (StAR) protein, while its N-terminal domain exhibits a function of targeting the protein to late endosomes. MLN64 is likely to be involved in cholesterol transport and synthesis of steroid hormones. MLN64 gene, coamplified with C-erbB-2, is overexpressed in certain breast carcinomas and exerts an influence on biological characteristics of breast cancer cells. The high levels of MLN64 observed in some breast carcinomas could contribute to the growth and progression of these tumors through increased intratumoral steroidogenesis, and is considered as a predictive factor of breast cancer prognosis.
