Overview:
PFTK1, also known as PFTAIRE protein kinase 1, is a member of the CDC2 -related protein kinase family which is expressed primarily in the postnatal and adult nervous system (1). PFTK1 is highly expressed in brain, pancreas, kidney, heart, testis, and ovary. PFTK1 interacts with 14-3-3-beta, 14-3-3-epsilon, 14-3-3-eta and 14-3-3-tau. Using PFTK1 mutant constructs and in vitro and in vivo binding studies, it was shown that PFTK1 amino acid residue ser119 is required for its interaction with all four 14-3-3 isoforms. (2). Significant upregulation of PFTK1 expression is observed in oesophageal squamous cell carcinoma (ESCC). PFTK1 is not only useful as a prognostic marker in ESCC, but also as a predictor of the response to chemotherapy.

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。
