The Lurcher mutation, a point mutation of the GluRδ 2 subunit, converts it into a functional channel. We introduced this mutation into GluRδ, AMPA-and NMDA-type GluR channel subunits, and characterized their channel properties. It was shown that the Lurcher mutation exerts effects only on the AMPA-and NMDA-type channel gating, but not on their ionic channel permeabilities. These findings support the idea that the Lurcher mutant GluRδ 1 and GluRδ 2 channels are permeable to Ca^2+, reflecting their original channel properties. It was also found that the ionic permeability of the mutant GluRδ 1 channels was modulated by TPA.}, pages = {506--517}, title = {Lurcher型変異を用いたグルタミン酸受容体 δサブユニットのチャネル特性解析}, volume = {115}, year = {2001} }
