The splice variant combination in heteromeric receptor complexes determines the impact of γ2 on I_KA/I_Glu ratios

	GluR1(Q)o + GluR2(R)o	GluR1(Q)i + GluR2(R)i	GluR1(Q)o + GluR2(R)i	GluR1(Q)i + GluR2(R)o
—	37.5 ± 2.0	7.8 ± 0.9	5.6 ± 0.3	20.8 ± 2.3
γ2	41.9 ± 3.5	1.9 ± 0.1*	5.4 ± 0.5	8.4 ± 1.0*

Calculation was performed as described for Table 1. The nomenclature of the AMPA receptor subunits is explained in Table 1. n = 15–16.

*p < 0.005 compared with AMPA receptor subunits without TARP.
