1 The glycine site antagonist 5,7-[3H]dichlorokynurenic acid labeled a single high-affinity site (KD = 29.6 +/- 6 nM; Bmax = 19.4 +/- 1.6 pmol/mg of protein) in membranes derived from COS cells electroporated with NR1-1a. Glycine glutamate ionotropic receptor NMDA type subunit 1 L homeolog Xenopus laevis
2 Although expression of NR1-1a is sufficient to reconstitute a glycine binding site with wild-type affinity for antagonists in COS cells, recombinant homomeric NR1-1a receptors do not display properties that are characteristic of native NMDA receptors, such as permeability to Ca2+ and channel occupancy by MK-801, when expressed in this mammalian cell line. Glycine glutamate ionotropic receptor NMDA type subunit 1 L homeolog Xenopus laevis
