TMPRSS2基因突变因子与药物介绍
这个基因编码一种属于丝氨酸蛋白酶家族的蛋白质。编码的蛋白质包含一个II型跨膜结构域、一个受体A级结构域、一个清道夫受体富含半胱氨酸结构域和一个蛋白酶结构域。丝氨酸蛋白酶参与许多生理和病理过程。该基因在前列腺癌细胞中被雄激素上调，在雄激素非依赖性前列腺癌组织中下调。这种蛋白的蛋白酶结构域被认为是在细胞自裂解后被切割并分泌到细胞培养基中的。另外，已经发现该基因编码不同亚型的剪接转录变体。[由RefSeq提供，2008年9月]
This gene encodes a protein that belongs to the serine protease family. The encoded protein contains a type II transmembrane domain, a receptor class A domain, a scavenger receptor cysteine-rich domain and a protease domain. Serine proteases are known to be involved in many physiological and pathological processes. This gene was demonstrated to be up-regulated by androgenic hormones in prostate cancer cells and down-regulated in androgen-independent prostate cancer tissue. The protease domain of this protein is thought to be cleaved and secreted into cell media after autocleavage. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2008]
