Overview:
YES1 is the cellular homolog of the Yamaguchi sarcoma virus oncogene that has tyrosine kinase activity and belongs to the SRC family. YES1 lies in close proximity to thymidylate synthase gene on chromosome 18 and chromosome 22 (1). The activation of YES1 may play a significant role in the malignant transformation of hepatocytes and is important for maintaining embryonic stem cells in an undifferentiated state. YES1 is a useful marker to detect early-stage hepatocellular carcinoma and play a key role in the tumorigenesis and metastasis of gastric cancer.YES1 induction results in increased cancer cell motility suggesting that YES1 may promote cancer spread and metastasis rather than tumor growth (2).
Gene Aliases:
Yes, c-yes, HsT441, P61-YES
Genbank Number:
NM_005433

各位大侠:小弟最近做个长片段的CDNA与T载体的连接,片段大小6.4K,载体选用的是pUC19和pGEMT-easy,反转录酶用的是RevertAidTirstStrandcDNASynthesisKit(#K1621),CDNA第二链的扩增用的是LATaq。我是用纯病毒的RNA做模板,操作步骤严格按照说明做的,也曾经有一次获得过电泳图清晰显示的是全长6.4KB左右的片段,与载体连接,结果筛选到的几个克隆,插入的片段仅有2KB左右,奈何?可最近几次再用此反转录试剂盒却不能得到所需片段。在此,小弟想问问大家,你们是否遇到同样的问题,是如何解决的?所用的试剂(载体和酶的选择)和方法是什么,可以告诉后来者,共同进步吧。
