The encoded protein is enriched in the caudate nucleus and cerebellar cortex. A similar protein in mouse may be involved in regulating the effects of dopamine in the basal ganglia. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Jun 2012] Expression Biased expression in brain (RPKM 4.3) and esophagus (RPKM 0.1) See more Orthologs mouse all
