英文摘要
ATP receptor channel P2X_2 consists of three subunits, but it is known to be activated by binding of two ATP. The aim of this research was to understand how the activation signal by two ATP flows in the trimer. By establishing a method to introduce mutations controlling the number of mutations in the trimer, we introduced 1, 2 or 3 mutations at various amino acid residues in the trimer. The results suggested that the activation signal flows on the two ATP bound subunits down to the linker level and it spreads to three subunits at the ion channel pore level.
