pMD18-T Simple Vector Information

pMD18-T Simple Vector is a high-efficiency TA cloning vector constructed from pUC18, of which the initial multiple cloning sites (MCS) were destroyed. Thus the cDNA should be amplified by PCR with primers containing a restriction site for subclone. Competent cells appropriate for pUC18 are also appropriated for the Vector, e.g. JM109, DH5α, TOP10. The pMD18-T Simple Vector is 2.6kb in size. Selection of the plasmid in E. coli is conferred by the ampicillin resistance gene. The coding sequence was inserted by TA cloning at site 425.

pMD18-T Simple Usage Suggestion

The coding sequence can be amplified by PCR with M13-47 and RV-M primers.

Background

Prostasin (Prss8), also known as channel activating protease 1 (CAP1), is a trypsinlike serine peptidase, and plays important roles in epithelial physiology. It is originally purified as an active, soluble enzyme from human seminal fluid and is highly expressed in prostate, lung, kidney, salivary gland and pancreas. Prostasin is expressed as a glycosyl-phosphatidylinositol (GPI)-anchored membrane protein in prostate epithelial cells, and also exists as a secreted proteolytic enzyme possibly via tryptic cleavage of its COOH-terminal hydrophobic domain. Prostasin is found to activate the epithelial sodium channel (ENaC) which is tightly regulated and is critical for maintaining salt and fluid balance in the lung and kidney in both normal and pathological conditions. Accordingly, prostasin has been proposed as a target for therapeutic inhibition in cystic fibrosis. In addition, prostasin inhibits prostate and breast cancer cell invasion in vitro, suggesting a functional role as a suppressor of tumor invasion, as well as a regulator of gene expression during inflammation.
