Abstract

The results described here demonstrate that Xenopus oocytes endogenously express a unitary glutamate receptor subunit XenU1. The level of XenU1 mRNA expression reaches approximately 1/300 of that in the adult Xenopus brain. The endogenous expression of XenU1, which can functionally interact with N-methyl-D-aspartate receptor subunit NR1, explains the differences in NR1 subunit expression in mammalian cell lines (no functional expression without partner subunits) and in the Xenopus oocytes (NR1 forms functional receptors when expressed singly).
