β-分泌酶1 (EC 3.4.23.46) (天冬氨酰蛋白酶2) (ASP2) (Asp 2) (β-位点淀粉样前体蛋白裂解酶1) (β-位点APP裂解酶1) (膜天冬酶-2) (膜相关天冬氨酸蛋白酶2)

P56817

功能描述

负责淀粉样前体蛋白 (APP) 的蛋白水解加工。在A-beta肽序列的N端切割,位于APP的671和672残基之间,导致beta切割的可溶性APP的生成和胞外释放,以及相应的细胞相关C端片段,该片段随后被gamma-secretase释放 (PubMed:10656250, PubMed:10677483, PubMed:20354142)。切割CHL1 (根据相似性)。 {ECO:0000250|UniProtKB:P56818, ECO:0000269|PubMed:10656250, ECO:0000269|PubMed:10677483, ECO:0000269|PubMed:20354142}。

组织特异性

Expressed at high levels in the brain and pancreas. In the brain, expression is highest in the substantia nigra, locus coruleus and medulla oblongata.
