| Gene Symbol | HTR1D |
| Full Name | 5-Hydroxytryptamine Receptor 1D |
| Chromosomal Location | 1p36.12 |
| NCBI Gene ID | 3352 |
| Ensembl ID | ENSG00000168594 |
| UniProt ID | P28221 |
| Gene Family | 5-HT1 receptor family (GPCR) |
| Protein Class | G protein-coupled receptor |

The HTR1D gene encodes the 5-hydroxytryptamine receptor 1D (5-HT1D), a G protein-coupled receptor that plays a critical role in migraine pathophysiology. This receptor is the primary target of triptan-class antimigraine drugs and regulates neurotransmitter release in the trigeminovascular system.
The HTR1D gene is located on chromosome 1p36.12 and encodes a 377-amino acid protein. The receptor contains seven transmembrane domains typical of GPCRs and couples to Gi/o proteins, inhibiting adenylate cyclase and reducing cAMP production.
5-HT1D receptors are expressed in:
| Drug | Formulation | Onset | Duration |
|---|---|---|---|
| Sumatriptan | Oral, injection, nasal | Fast | Short |
| Zolmitriptan | Oral, nasal | Fast | Medium |
| Rizatriptan | Oral | Fast | Medium |
| Eletriptan | Oral | Fast | Long |
| Frovatriptan | Oral | Slow | Long |
The study of Htr1D Gene has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development.
Historical context and key discoveries in this field have shaped our current understanding and will continue to guide future research directions.
