[5][6][7] Elastases form a subfamily of serine proteases that hydrolyze many proteins in addition to elastin.

Like most of the human elastases, elastase 3A is secreted from the pancreas as a zymogen and, like other serine proteases such as trypsin, chymotrypsin and kallikrein, it has a digestive function in the intestine.

Elastase 3A preferentially cleaves proteins after alanine residues.

Elastase 3A may also function in the intestinal transport and metabolism of cholesterol.
