Overview:
SUMO1 (also known as UBL1) is a member of the SUMO (small ubiquitin-like modifier) protein family which functions in a manner similar to ubiquitin. SUMO1 is bound to target proteins as part of a post-translational modification system and it is involved in a variety of cellular processes, such as nuclear transport, transcriptional regulation, apoptosis, and protein stability (1). SUMO1 may be involved in the repair of TOP1-mediated DNA damage (2). The sumoylation pathway plays a significant role in mammalian DNA damage response.

实验非常不顺,想构建CDNA文库,但是从mRNA开始屡次失败,考虑主要是纯化过程中损失过多。想从总RNA入手,但是不知道实验步骤。不知那位大侠能提供总RNA建库的实验步骤。另外我现在手头有OligoDT,RT酶,苦于没有第二连合成试剂盒,不知道能否用普通PCR试剂盒Teq酶替代第二链合成过程中的DNA聚合酶I。好像有种方法合成第二链时,不需要另外的引物,利用降解的RNA作引物即可,我想直接设定PCR两个循环,合成第二链,不知方法可行否?愁啊,等着毕业,时间紧急,恳请帮忙。谢谢。
