功能概要

氨基己糖苷酶 B 是溶酶体酶 β-氨基己糖苷酶的 β 亚基,它与辅助因子 GM2 激活蛋白一起催化神经节苷脂 GM2 和其他含有末端 N-乙酰己糖胺的分子的降解。 β-己糖胺酶由两个亚基 alpha 和 beta 组成,它们由不同的基因编码。 β-己糖胺酶 α 和 β 亚基都是糖基水解酶家族 20 的成员。 α 或β 亚基基因的突变导致 GM2 神经节苷脂在神经元和神经退行性疾病中的积累,称为 GM2 神经节苷脂增多症。 β 亚基基因突变导致 Sandhoff 病 (GM2-神经节苷脂病 II 型) 。已发现该基因编码不同亚型的可变剪接转录物变体。[RefSeq 提供,2014 年 5 月]

Hexosaminidase B is the beta subunit of the lysosomal Enzyme beta-hexosaminidase that, together with the cofactor GM2 activator protein, catalyzes the degradation of the ganglioside GM2, and other molecules containing terminal N-acetyl hexosamines. Beta-hexosaminidase is composed of two subunits, alpha and beta, which are encoded by separate genes. Both beta-hexosaminidase alpha and beta subunits are members of family 20 of glycosyl hydrolases. Mutations in the alpha or beta subunit genes lead to an accumulation of GM2 ganglioside in neurons and neurodegenerative disorders termed the GM2 gangliosidoses. Beta subunit gene mutations lead to Sandhoff disease (GM2-gangliosidosis type II). Alternatively spliced transcript variants encoding different isoforms have been found for this gene.
