background:
NETO1 is a 533 amino acid protein that contains one LDL-receptor class A domain and two CUB domains and is either membrane-bound or secreted. Expressed as three alternatively spliced isoforms, the first two of which are retina-specific and the third of which is found in both retina and brain tissue, NETO1 is thought to be involved in the development and maintenance of neuronal circuitry, possibly playing a role in proper brain function. Human NETO1 shares 95% amino acid identity with its mouse counterpart, suggesting a conserved role between species. The gene encoding NETO1 maps to human chromosome 18, which houses over 300 protein-coding genes and contains nearly 76 million bases. There are a variety of diseases associated with defects in chromosome 18-localized genes, some of which include Trisomy 18 (also known as Edwards syndrome), Niemann-Pick disease, hereditary hemorrhagic telangiectasia, erythropoietic protoporphyria and follicular lymphomas.
Function:
Involved in the development and/or maintenance of neuronal circuitry. Accessory subunit of the neuronal N-methyl-D-aspartate receptor (NMDAR) critical for maintaining the abundance of GRIN2A-containing NMDARs in the postsynaptic density. Regulates long-term NMDA receptor-dependent synaptic plasticity and cognition, at least in the context of spatial learning and memory.
Subunit:
Interacts with PLZ domains of DLG2, DLG3 and DLG4 via its SLCterminal TRV domain. Interacts with GRIN2A and GRIN2B via its CUB domains.
Subcellular Location:
Isoform 2: Cell membrane; Single-pass type I membrane protein (Potential). Cell junction, synapse, postsynaptic cell membrane, postsynaptic density. Note=Component of the postsynaptic density (PSD) of excitatory synapses. Isoform 3: Cell membrane; Single-pass type I membrane protein (Potential).Isoform 1: Secreted (Potential).
Tissue Specificity:
Isoform 1 and isoform 2 are retina-specific. Isoform 3 is found in retina as well as at lower levels in adult and fetal brain.
Similarity:
Contains 2 CUB domains.
Contains 1 LDL-receptor class A domain.
