Summaries for AMY1A Gene

Entrez Gene Summary for AMY1A Gene

  • 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 (Salivary)) is a Protein Coding gene. Diseases associated with AMY1A include Developmental Coordination Disorder and Sick Building Syndrome. Among its related pathways are Glycosaminoglycan metabolism and Digestion of dietary carbohydrate. GO annotations related to this gene include cation binding and alpha-amylase activity. An important paralog of this gene is AMY2B.
