Summaries for PRSS2 Gene

Entrez Gene Summary for PRSS2 Gene

  • This gene belongs to the trypsin family of serine proteases and encodes anionic trypsinogen. It is part of a cluster of trypsinogen genes that are located within the T cell receptor beta locus. Enzymes of this family cleave peptide bonds that follow lysine or arginine residues. This protein is found at high levels in pancreatic juice and its upregulation is a characteristic feature of pancreatitis. This protein has also been found to activate pro-urokinase in ovarian tumors, suggesting a function in tumor invasion. In addition, this enzyme is able to cleave across the type II collagen triple helix in rheumatoid arthritis synovitis tissue, potentially participating in the degradation of type II collagen-rich cartilage matrix. Alternative splicing results in multiple transcript variants.[provided by RefSeq, Jan 2015]

Post-translational modifications for PRSS2 Gene

  • Sulfated on tyrosine.
  • Sulfation at Tyr-154 increases selectivity towards basic versus apolar residues at the P2' position of inhibitors that bind in a substrate-like fashion. Although the increase in selectivity is relatively small, it may facilitate digestion of a broader range of dietary proteins.
