SUBCELLULAR LOCALIZATION	extracellular
	plasma membrane

basic FUNCTION	may be involved in intracellular signaling pathway
	having roles during development of the central nervous system
	regulates NMDA receptor-dependent synaptic plasticity and cognition
	have marked effects on receptor properties, increasing further the potential diversity of KAR (Kainate receptor) functional properties
	by regulating kainate receptor excitatory postsynaptic current kinetics, NETO1 can control synaptic temporal summation, spike generation and fidelity
	the ability of NETO1 to regulate both NMDARs and kainate receptors reveals a unique dual role in controlling synaptic transmission by serving as an auxiliary protein for these two classes of ionotropic glutamate receptors in a synapse-specific fashion
	NETO1, and NETO2 are auxiliary subunits that determine key properties of native kainate receptors
	NETO1, and NETO2 transmembrane proteins alter the trafficking, channel kinetics, and pharmacology of the receptors in a subunit-dependent manner
	NETO1 and NETO2 auxiliary subunits coassemble with NMDA receptors (NMDARs) and kainate receptors (KARs) to modulate their function
