Secondary Information

Protein Function circulating enzyme that reduces platelet hyperactivation, triggers both insulin secretion and degradation, and increases insulin sensitivity.
Biochemical Properties exocrine pancreatic elastase that preferentially cleaves A-acetyl-L-alanyl-L-alanyl-L-alanine/proline methyl-ester.There is a C-to-A transversion (chr1.15,789,253C-A, GRCh37) in the CELA2A gene, resulting in a leu85-to-met (L85M) substitution at a highly conserved residue within the catalytic domain which is the cause of ABDOMINAL OBESITY-METABOLIC SYNDROME 4.The catalytic triad is made up of his45, asp93, and ser188.
