- Overview
  - CTSE Human Recombinant produced in E. Coli is a single, non-glycosylated polypeptide chain containing 330 amino acids (57-363 a.a) and having a molecular mass of 35.4kDa. CTSE is fused to a 23 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques. Cathepsin-E also known as CTSE is a gastric aspartyl protease which functions as a disulfide-linked homodimer. CTSE belongs to the peptidase C1 family; furthermore it has specificity similar to pepsin A and cathepsin D. CTSE is an intracellular proteinase which does not seem to be involved in the digestion of dietary protein and is found in the upper most concentration in the surface of epithelial mucus-producing cells of the stomach. CTSE is the first aspartic proteinase expressed in the fetal stomach and is discovered in more than half of gastric cancers. For that reason CTSE is an oncofetalantigen. In addition, transcript variants utilizing alternative polyadenylation signals and two transcript variants encoding different isoforms exist for this gene.
