title: Molecular size of the high-affinity glutamate-binding site on synaptic membranes from rat brain.
abstract: We have used radiation inactivation as a means of determining the molecular size of the high-affinity glutamate-binding site on rat brain synaptic membranes. The molecular size was 75,000 +/- 15,000 in the absence of glutamate and 263,000 +/- 34,000 in the presence of glutamate. These data may be interpreted as suggesting that the high-affinity glutamate-binding site is comprised of a number of subunits. The minimum sub-unit size detected by this method was 75,000 +/- 15,000.
