物理属性
牛肝脏中的蛋白质二硫键异构酶 (PDI) 是一种分子量为 107 kDa 的同源二聚体（凝胶过滤），已报告单体的分子量为 57 kDa (SDS-PAGE)。该酶是总碳水化合物含量为 12% 的糖蛋白，由 4.6% 的甘露糖、2.5% 的半乳糖、1.4% 的 NANA 和 3.5% 的 2-乙酰胺基-2-脱氧葡萄糖组成。
单位定义
1 unit corresponds to the amount of enzyme, which, in a glutathione-dithiothreitol-system, causes a change of absorbance of 0.001 per minute at pH 4.0 and 25°C.

Anterior gradient 2 (AGR2) is a normal endoplasmic reticulum protein that has two important abnormal functions, amphibian limb regeneration and human cancer metastasis promotion. These normal intracellular and abnormal extracellular roles can be attributed to the multidomain structure of AGR2.

Tapasin is an integral component of the peptide-loading complex (PLC) important for efficient peptide loading onto MHC class I molecules. We investigated the function of the tapasin-related protein, TAPBPR. Like tapasin, TAPBPR is widely expressed, IFN-γ-inducible, and binds to MHC

About one-third of all cellular proteins pass through the secretory pathway and hence undergo oxidative folding in the endoplasmic reticulum (ER). Protein-disulfide isomerase (PDI) and related members of the PDI family assist in the folding of substrates by catalyzing the

Anterior Gradient 2 (AGR2), an ER stress-inducible protein, has been reported to be localized in endoplasmic reticulum (ER) and its level is elevated in numerous metastatic cancers. Recently, it has been demonstrated that AGR2 is involved in the control of

The stability of the MHC (major histocompatibility complex) class I peptide repertoire is optimized during assembly in the endoplasmic reticulum (ER) and depends on the collective function of components of the peptide-loading complex (PLC). The chaperone-like molecule tapasin is the
