NCSTN

该基因编码一种I型跨膜糖蛋白，是多聚γ分泌酶复合物的组成部分。编码的蛋白质可切割完整的膜蛋白，包括notch受体和β-淀粉样前体蛋白，可能是γ-分泌酶复合物组装所需的稳定辅助因子。β-淀粉样蛋白前体蛋白的裂解产生β-淀粉样肽，它是阿尔茨海默病患者大脑中神经斑块和标志性病变的主要成分；然而，编码蛋白在阿尔茨海默病中作用的性质尚不清楚该基因突变与家族性痤疮反转有关。这个基因的假基因存在于21号染色体上。已经描述了该基因的选择性剪接转录变体，但其中一些变体的全长性质尚未确定。[由RefSeq提供，2014年2月]
This gene encodes a type I transmembrane glycoprotein that is an integral component of the multimeric gamma-secretase complex. The encoded protein cleaves integral membrane proteins, including Notch receptors and beta-amyloid precursor protein, and may be a stabilizing cofactor required for gamma-secretase complex assembly. The cleavage of beta-amyloid precursor protein yields amyloid beta peptide, the main component of the neuritic plaque and the hallmark lesion in the brains of patients with Alzheimer's disease; however, the nature of the encoded protein's role in Alzheimer's disease is not known for certain. Mutations in this gene are associated with familial acne inversa. A pseudogene of this gene is present on chromosome 21. Alternatively spliced transcript variants of this gene have been described, but the full-length nature of some of these variants has not been determined. [provided by RefSeq, Feb 2014]
