Tissue SpecificityWidely expressed in adult and fetal tissues with highest expression in adult brain (at protein level), heart, liver and adrenal gland and fetal heart, kidney, liver and lung. Expressed in presynaptic terminals of dopaminergic neurons projecting from the substantia nigra pars compacta to the striatum (at protein level) (PubMed:17296554). Expressed in axonal varicosities in dopaminergic nerve terminals (at protein level) (PubMed:17296554). Expressed in the putamen and in the adjacent cerebral cortex (at protein level) (PubMed:17296554). Expressed in colonic crypts (at protein level) (PubMed:30389919). Also expressed in colorectal cancers and malignant melanomas. Expressed in platelets. {ECO:0000269|PubMed:11146656, ECO:0000269|PubMed:11167005, ECO:0000269|PubMed:11511094, ECO:0000269|PubMed:15116257, ECO:0000269|PubMed:15915442, ECO:0000269|PubMed:17296554, ECO:0000269|PubMed:30389919, ECO:0000269|PubMed:9889007}.;
[Isoform ARTS]: Highly expressed in the brain and heart. {ECO:0000269|PubMed:11146656}.
