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 salivary gland. Alternative splicing results in multiple transcript variants encoding the same protein. [provided by RefSeq, Jul 2008]
GeneCards Summary for AMY1A Gene
AMY1A (Amylase Alpha 1A) is a Protein Coding gene. Diseases associated with AMY1A include Stereotypic Movement Disorder and Major Depressive Disorder. Among its related pathways are Salivary secretion and Glycosaminoglycan metabolism. Gene Ontology (GO) annotations related to this gene include cation binding and alpha-amylase activity. An important paralog of this gene is AMY1B.
UniProtKB/Swiss-Prot Summary for AMY1A Gene
Calcium-binding enzyme that initiates starch digestion in the oral cavity (PubMed:12527308). Catalyzes the hydrolysis of internal (1->4)-alpha-D-glucosidic bonds, yielding a mixture of maltose, isomaltose, small amounts of glucose as well as small linear and branched oligosaccharides called dextrins (PubMed:12527308).
