Function
This gene encodes the D2 subtype of the dopamine receptor. This G protein-coupled receptor inhibits adenylyl cyclase activity.
Alternative splicing of this gene results in two transcript variants encoding different isoforms. A third variant has been described, but it has not been determined whether this form is normal or due to aberrant splicing.
In mice, regulation of D2R surface expression by the calcium sensor NCS-1 in the dentate gyrus controls exploration, synaptic plasticity and memory formation.
