Receptor protein levels are unchanged in α-neurexin KO mice. Immunoblot analysis of comparable amounts of proteins from control (SKO) and TKO slice cultures. Each lane contains proteins from pooled 10- to 12-slice cultures established from a single mouse. Signals were detected by enhanced chemiluminescence. NR, NMDA-receptor subunit; phospho-NR, phosphorylated NMDA receptor; GluR1 and -R2/3, AMPA-type glutamate receptor subunits 1 and 2/3; HSP, heat-shock protein (loading control). See Table 1 for a quantitation of protein levels in brain homogenates.
