Recombinant protein corresponding to Ile24-Asp241 of human PRSS2, expressed in E. coli.
Trypsin (EC 3.4.21.4) is a serine protease found in the digestive system of many vertebrates, where it hydrolyses proteins.Rowen et al. (1996) mapped the gene corresponding to the third pancreatic trypsinogen cDNA by fluorescence in situ hybridization. They used a cosmid clone containing 3 trypsinogen genes. Strong hybridization to chromosome 7 and weaker hybridization to chromosome 9 were observed. They isolated and partially sequenced 4 cosmid clones from the chromosome 9 region. They found that the region represents a duplication and translocation of a DNA segment from the 3-prime end of the TCRB locus that includes at least 7 V(beta) elements and a functional trypsinogen gene denoted T9.
