中文摘要
ryanodine受体/Ca^<2+>释放通道的疾病相关突变使该通道过度激活。区域间相互作用被认为参与了过度激活的机制。在这里,我们通过纳米金标记和FRET检查了子域1和子域2之间的相互作用。我们发现子域1和子域2位置很近,并且相互作用。此外,子结构域3的突变可能通过改变S4-S5连接子的相互作用来影响通道门控。
英文摘要
Disease-associated mutations in ryanodine receptor/Ca^<2+> release channel hyperactivate the channel. Interdomain interaction is proposed to be involved in the mechanism of hyperactivation. Here, we examined interaction between subdomains 1 and 2 by nanogold labeling and FRET. We found that subdomains 1 and 2 are closely located and interact to each other. In addition, mutations in subdomain 3 may affect the channel gating by altering the interaction via the S4-S5 linker.
