  copper binding proteins
Two proteins related to neurodegenerative diseases have been described as copper binding proteins: the amyloid precursor protein (APP), a protein related to Alzheimer's disease, and the Prion protein (PrP), related to Creutzfeldt-Jakob disease.
      
In fact, copper binding proteins that form bioinorganic complexes are able to display oxidant or anti-oxidant properties, which would impact on neuronal function or in the triggering of neurodegenerative process.
      
Copper reduction by copper binding proteins and its relation to neurodegenerative diseases
      
The metabolism of copper, once within the organism, deals with copper-binding proteins which act as transport agents.
      
Swiss-Prot, a tool provided on the EBI website, was used to identify copper-binding proteins from an existing protein database.

Ssveral experiments have been done to demonstrate molybdate sulphur and their compound-trithiomolybdate could affect the metabolism of copper bound proteins in liver cytosol, especially copper on the metallothioncin. A possibility is that molybdate strip copper from metallothionein in the cytosol of liver of cattle. Copper stripped either moved out of cells as a small molecullar compound in vivo, or combined to a large molecullar proteins in cytosol in vitro. Meanwhile, metallothionein...

Ssveral experiments have been done to demonstrate molybdate sulphur and their compound-trithiomolybdate could affect the metabolism of copper bound proteins in liver cytosol, especially copper on the metallothioncin. A possibility is that molybdate strip copper from metallothionein in the cytosol of liver of cattle. Copper stripped either moved out of cells as a small molecullar compound in vivo, or combined to a large molecullar proteins in cytosol in vitro. Meanwhile, metallothionein may capture copper from other source, for example, a large molecullar copper bound proteins. The peak of metallothionein appcars when thiomolybdate excreted from cells. Dithiothretol can stablize the combination of copper to metallothionein. There is no obvious effect on the combination of copper to the proteins when samples were stored in -20℃ for five weeks.

以8头公犊为材料,通过体内和体外试验证明硫、钼及其化合物三硫钼酸盐被吸收或直接注入血液进入肝脏后,对肝内铜代谢的干扰作用主要是促使铜与咪噻宁蛋白质分离。分离后的铜成为小分子化合物离开肝细胞,而在体外试验中,还有部分铜转移到分子量较大的蛋白质上。一旦硫钼酸盐从肝内排泄后,体内铜很快与咪噻宁重新结合。缓冲液中二硫苏糖醇可使铜与咪噻宁结合保持恒定,样品在冰冻情况下保存5周,对咪噻宁与铜结合作用无明显影响。

To inquire into the relationship between iron,copper,HBV and hepatocelluar carcinoma(HCC),we collected 70 storing Paraffin blocks of patients with cirrhosis and HCC and 10 normal controlblocks.and surveyed them with methods of cytochemistry and image analysis technique (IAT).The relativecontent of hepatic iron was significantly higher in positive HBsAg group than in negative group (P<0. 05). Itindicated that there was a close relationship between HBV and iron. Distribution of iron granule.was even innormal...

To inquire into the relationship between iron,copper,HBV and hepatocelluar carcinoma(HCC),we collected 70 storing Paraffin blocks of patients with cirrhosis and HCC and 10 normal controlblocks.and surveyed them with methods of cytochemistry and image analysis technique (IAT).The relativecontent of hepatic iron was significantly higher in positive HBsAg group than in negative group (P<0. 05). Itindicated that there was a close relationship between HBV and iron. Distribution of iron granule.was even innormal liver. exttemely uneven in cirrhosis and always negative in HCC.We found a siderotic macroregenerative nodule(MRN) within which there was an iron-negative lesion of HCC. We considered that the appearance of "nodule within nodule" was the early stage of canceration and iron acted as an improving factor toHCC. In addition. we found that granules of copper and copper-binding protein (CBP) were related to inflammation and fibrosis and appeared mainly in well-differentiated HCC. It is concluded that the effects ofcopper were different from those of iron to HCC.

为探讨铁、铜、乙肝病毒与肝癌的关系,利用组化染色及图像分析技术对贮存的70例肝癌、肝硬化标本蜡块及10例正常对照标本进行了观测分析.HBsAg阳性组肝铁含量显著高于阴性组(P<0.05).提示HBV与铁关系密切.正常肝铁分布均匀;肝硬化铁分布参差不一,与肝细胞增生有关;肝癌细胞内无铁颗粒.与周围肝细胞形成了明显的界线.有铁聚集的肝再生巨结节(MRN)中出现的“灶中灶”结构可能为肝硬化癌变的初始阶段表现,铁可能有促癌作用.铜颗粒的出现与炎性反应、纤维组织增生等有关,常出现于分化较好的肝癌细胞内,其作用不同于铁.

Objective: To isolate copper binding protein from rat liver lysosomal fraction, and to analyze its amino acid sequences. Methods: G25-chromatography, copper-chelating chromatography, high performance liquid chromatography, amino acid sequencing were used. Results:We isolated copper binding protein from rat liver lysomal fraction; Two bands of protein of 58kDa and 40kDa were observed. Amino acid sequence was A-F-Q-I-L-Y-L-T-H-N-L. Homology search showed the protein was a novel protein....
