Background
Chymotrypsin C(CTRC), also known as caldecrin, is a serine protease and a member of the peptidase S1 family. The CTRC gene encodes a serum calcium-decreasing factor that has chymotrypsin-like protease activity (1). CTRC has broad substrate specificity, but prefers to cleave on the carboxyl side of hydrophobic residues. The enzyme is expressed primarily in the pancreas, and is secreted into the digestive tract. CTRC is a key regulator of activation and degradation of cationic trypsinogen (2, 3). The inappropriate activation of cationic trypsinogen can contribute to the development of pancreatitis (2, 3). CTRC inhibits osteoclast differentiation by suppression of NFATc1 function by a mechanism independent of its proteolytic activity (4).
