糖基水解酶水解兩種或多種碳水化合物之間或碳水化合物和非碳水化合物部分之間的糖苷鍵。該基因編碼糖基水解酶家族31的一個成員這種酶水解末端的非還原1,4-連接的α-d-葡萄糖殘基并釋放α-d-葡萄糖。這是糖原代謝中的關鍵酶，其基因定位于與糖尿病易感性相關的染色體區域（15q15）。選擇性剪接導致編碼不同亞型的多個轉錄變體[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]
