這個基因編碼一種胰蛋白酶原，它是絲氨酸蛋白酶家族的一員。這種酶由胰腺分泌，在小腸內分裂成活性形式。它對涉及賴氨酸或精氨酸的羧基的肽鍵具有活性。該基因突變與遺傳性胰腺炎有關。這個基因和其他一些胰蛋白酶原基因定位在7號染色體上的T細胞受體β位點。[由RefSeq提供，2008年7月]
This gene encodes a trypsinogen, which is a member of the trypsin family of serine proteases. This enzyme is secreted by the pancreas and cleaved to its active form in the small intestine. It is active on peptide linkages involving the carboxyl group of lysine or arginine. Mutations in this gene are associated with hereditary pancreatitis. This gene and several other trypsinogen genes are localized to the T cell receptor beta locus on chromosome 7. [provided by RefSeq, Jul 2008]
