产品描述

种属	Human
表达系统	HEK293
标签	His,AVI
蛋白编号	O95484
蛋白构建	A DNA sequence encoding the human CLDN9 (O95484) (Met1-Thr184) was expressed, with a polyhistidine tag followed by an AVI tag at the C-terminus. The expressed protein was biotinylated in vivo by the Biotin-Protein ligase (BirA enzyme) which is co-expressed.Nanodisc is a versatile tool for studying membrane proteins. Using styrene-maleic acid (SMA) copolymer, membrane proteins can be extracted directly from prokaryotic and eukaryotic expression systems in the absence of detergents to preserve the protein structure and function better. Compared to membrane scaffold proteins (MSPs) nanodiscs, SMA nanodiscs also have the advantage of preserving proteins' nature by maintaining native lipids surrounded without introducing any heterologous proteins, which allows studies of protein structure and functions in a native-like environment.

研究背景	Claudin-9 (CLDN9) belongs to the claudins family and is a transmembrane protein found in tight junctions with two extracellular loops and a cytoplasmic C tail. CLDN9 modulates the ion- and charge-specific permeability of the paracellular pathway in most epithelial tissues. It forms heterotypic interactions with other claudins to create cation-selective channels in the kidney and may contribute to the maintenance of alveolar barrier function in the lung. Deficiency is shown to be associated with autosomal recessive deafness, DFNB116. CLDN9 expression has been shown to be upregulated in certain types of cancer, such as endometrial cancer and hepatocellular carcinoma, and its knockdown has been found to reduce cell proliferation and migration in vitro.
