The potency of Pb2+ inhibition of glutamate-activated currents mediated by N-methyl-D-aspartate (NMDA) receptors was dependent on the subunits composing the receptors when functionally expressed in Xenopus laevis oocytes. Pb2+ reduced the amplitudes of glutamate-activated currents and shifted the agonist EC50 values of NMDA receptors consisting of different subunit compositions. The IC50 values...
