| 产品介绍 | The nuclear lamina consists of a two-dimensional matrix of proteins located next to the inner nuclear membrane. The lamin family of proteins make up the matrix and are highly conserved in evolution. During mitosis, the lamina matrix is reversibly disassembled as the lamin proteins are phosphorylated. Lamin proteins are thought to be involved in nuclear stability, chromatin structure and gene expression. Vertebrate lamins consist of two types, A and B. This gene encodes one of the two B type proteins, B1. Alternative splicing results in transcript variants and a duplication of this gene is associated with autosomal dominant adult-onset leukodystrophy (ADLD). [provided by RefSeq, Oct 2010]. Function: Lamins are components of the nuclear lamina, a fibrous layer on the nucleoplasmic side of the inner nuclear membrane, which is thought to provide a framework for the nuclear envelope and may also interact with chromatin. Subunit: Homodimer. Interacts with lamin-associated polypeptides IA, IB and 2. Subcellular Location: Nucleus inner membrane; Lipid-anchor; Nucleoplasmic side. Post-translational modifications: B-type lamins undergo a series of modifications, such as farnesylation and phosphorylation. Increased phosphorylation of the lamins occurs before envelope disintegration and probably plays a role in regulating lamin associations. DISEASE: Defects in LMNB1 are the cause of leukodystrophy demyelinating autosomal dominant adult-onset (ADLD) [MIM:169500]. ADLD is a slowly progressive and fatal demyelinating leukodystrophy, presenting in the fourth or fifth decade of life. Clinically characterized by early autonomic abnormalities, pyramidal and cerebellar dysfunction, and symmetric demyelination of the CNS. It differs from multiple sclerosis and other demyelinating disorders in that neuropathology shows preservation of oligodendroglia in the presence of subtotal demyelination and lack of astrogliosis. Similarity: Belongs to the intermediate filament family.

文献和实验脊椎动物细胞中有三种类型的核纤层蛋白(A,B,C), 核纤层蛋白A和C是由同一个转录单位编码的, 只不过是通过可变剪接形成不同的mRNA。它们在肽链上的差别是:核纤层蛋白A的C末端比核纤层蛋白C的C末端多133个氨基酸残基。核纤层蛋白B是由另一个转录单位编码的, 通过转录后的修饰,在羧基端添加了疏水的异丙基, 添加的脂肪酸帮助核纤层蛋白B插入到核膜的内脂层。三种类型的核纤层蛋白都以二聚体的形式存在, 有球形的头和尾部结构域以及一个杆状的α螺旋中心。这些核纤层蛋白二聚体以头-头、尾-尾相接
度蛋白质检测和研究诊断平台,可以分析多种 AD 生物标志物。其技术的原理是基于 ELISA 双抗体夹心方法,能够在飞升大小的孔中捕获单个分子,并通过“数字”读出其中的珠子是否与其对应的分析物结合。 ② SPR 是一种强大的光学检测技术,可用于实时研究无标记生物分子之间的相互作用。光源穿过棱镜,从检测表面的背面反射,然后进入检测器。在一定的入射角下,光被传感器芯片金属膜中的电子吸收,引起共振。由于反射光束强度的损失,它表现为暗带,可以看作是 SPR 反射强度曲线的下降。由于 SPR 浸渍的形状和位置
生理状态或病理状态下蛋白水平的量变,微型化,集成化,高通量化的抗体芯片就是一个非常好的研究工具,它也是蛋白芯片中发展最快的芯片,而且在技术上已经日益成熟。这些抗体芯片有的已经在向临床应用上发展,比如肿瘤标志物抗体芯片等,还有很多已经用在研究的各个领域里。第一张商品化的抗体芯片是由美国BD Clontech公司推出的。这是一张用于研究的抗体芯片,芯片上排列了378种已知蛋白的单抗(Ab Microarray 380,目录号 K1847-1),这些单抗对应的蛋白都是细胞结构和功能上十分重要的蛋白,涉及信号
