Study on the correlation between membrane protein Flotillin-1 and PrPc endocytosis / 中华实验和临床病毒学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To explore whether the membrane-associated protein Flotillin-1 has relationship with endocytosis of PrPc.</p><p><b>METHODS</b>The expression of Flotillin-1 in different cell lines was detected with the method of Western Blot; the interaction between Flotillin-1 and PrPc in Cells which were treated with copper ions was observed using immunoprecipitation method.</p><p><b>RESULTS</b>(1) Flotillin-1 was widely expressed in many cell lines without significant difference in the amounts of expression level; (2) Only in the appearance of copper ions, the protein complexes of PrPc and Flotillin-1 can be detected with the method of IP, which were related to copper ions concentration and processing time.</p><p><b>CONCLUSION</b>The membrane-associated protein Flotillin-1 has the relationship with the endocytosis of PrPc.</p>
