Gene Information

human ... SPINK1(6690)

General description

Serine protease inhibitor Kazal-type 1 (UniProt P00995; also known as Pancreatic secretory trypsin inhibitor, TATI, Tumor-associated trypsin inhibitor) is encoded by the SPINK1 (also known as PCTT, PSTI, TCP) gene (Gene ID 6690) in human. Serine protease inhibitor Kazal-type 1 encoded by the human SPINK1 gene functions as an acute-phase protein (APP) in the pancreas. Produced initially in a 79-a.a. proform, the signal peptide (a.a. 1-23) is removed posttranslationally to yield the 56-a.a. (a.a. 24-79) mature protein. SPINK1 protein blocks premature activation of trypsinogen (inactive form of trypsin), thereby ensuring the integrity of acinar cells to prevent auto-digestion of the pancreas. SPINK1 is also reported to play a role in tissue repair, apoptosis, reproduction, and behave as a growth factor in other human organs. In addition, SPINK1 protein is known as tumor-associated trypsin inhibitor or TATI and current research activities are focused on the association of various cancers to deregulated SPINK1 activity.

Specificity

Expected to react with both pro- and mature human SPINK1.

Immunogen
