| Function | Positively regulates nitric oxide synthesis in umbilical vein endothelial cells (HUVECs). May be involved in dopamine synthesis. May modify pain sensitivity and persistence. Isoform GCH-1 is the functional enzyme, the potential function of the enzymatically inactive isoforms remains unknown. {ECO:0000269|PubMed:12176133, ECO:0000269|PubMed:16338639, ECO:0000269|PubMed:17057711, ECO:0000269|PubMed:8068008, ECO:0000269|PubMed:9445252}. |
| Subcellular Location | Cytoplasm. Nucleus. |
| Tissue Specificity | In epidermis, expressed predominantly in basal undifferentiated keratinocytes and in some but not all melanocytes (at protein level). {ECO:0000269|PubMed:16778797}. |
| Top Pathways | Folate biosynthesis |
