occurs in establishment of localization in cell postsynapse neurotransmitter receptor cycle postsynaptic neurotransmitter receptor cycle The process during which neurotransmitter receptors in the postsynaptic specialization membrane are recycled via the endosome. This cycle includes release from anchoring (trapping), diffusion in the synaptic membrane to the postsynaptic endocytic region, endocytosis, transport to the endosome, recycling in the endosome, transport back the synaptic membrane and subsequent trapping in the postsynaptic specialization membrane.
