糖基水解酶水解两种或多种碳水化合物之间或碳水化合物和非碳水化合物部分之间的糖苷键。该基因编码糖基水解酶家族31的一个成员这种酶水解末端的非还原1,4-连接的α-d-葡萄糖残基并释放α-d-葡萄糖。这是糖原代谢中的关键酶，其基因定位于与糖尿病易感性相关的染色体区域（15q15）。选择性剪接导致编码不同亚型的多个转录变体[由RefSeq提供，2014年8月]
Glycosyl hydrolase enzymes hydrolyse the glycosidic bond between two or more carbohydrates, or between a carbohydrate and a non-carbohydrate moiety. This gene encodes a member of glycosyl hydrolases family 31. This enzyme hydrolyses terminal, non-reducing 1,4-linked alpha-D-glucose residues and releases alpha-D-glucose. This is a key enzyme in glycogen metabolism and its gene localizes to a chromosomal region (15q15) that is associated with susceptibility to diabetes. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Aug 2014]
