Amylases are secreted proteins that hydrolyze 1,4-alpha-glucoside bonds in oligosaccharides and polysaccharides, and thus catalyze the first step in digestion of dietary starch and glycogen. The human genome has a cluster of several amylase genes that are expressed at high levels in either salivary gland or pancreas. This gene encodes an amylase isoenzyme produced by the pancreas.

A study in humans demonstrated that the AMY2B is present in semen and vaginal secretion and is distinguishable from salivary alpha-amylase 1 by mass spectrometry [Van Steendam et al. DOI:10.1007/s00414-012-0747-x]. A review of forensic proteomics literature notes that the AMY2B is a protein marker found in saliva for body fluid identification [Alex et al. DOI:10.1016/j.scijus.2025.101320].
