TissueNA
Tissue SpecificityUbiquitously expressed (PubMed:10930503). Expressed in neocortex (PubMed:16616430). Widely expressed in the central nervous system with higher concentrations in caudal regions. Expressed by glutamatergic and GABAergic neurons together with astrocytes and other non-neuronal cells in the cerebral cortex (at protein level) (PubMed:15774260). {ECO:0000269|PubMed:10930503, ECO:0000269|PubMed:15774260, ECO:0000269|PubMed:16616430}.

Subcellular location [CC]Cell membrane {ECO:0000250|UniProtKB:Q9JHE5};
Multi-pass membrane protein {ECO:0000250|UniProtKB:Q9JHE5}. Note=Insulin promotes recruitment to the plasma membrane from a pool localized in the trans-Golgi network or endosomes. Enriched in the somatodendritic compartment of neurons, it is also detected at the axonal shaft but excluded from the nerve terminal. {ECO:0000250|UniProtKB:Q9JHE5}.
