| Gene Name | SLC6A4 | ||||||||

| KEGG Pathway | hsa:6532 | ||||||||
| Protein Family | Sodium:neurotransmitter symporter (SNF) (TC 2.A.22) family | ||||||||
| Protein Function |
Serotonin transporter whose primary function in the central nervous system involves the regulation of serotonergic signaling via transport of serotonin molecules from the synaptic cleft back into the pre-synaptic terminal for re-utilization. Plays a key role in mediating regulation of the availability of serotonin to other receptors of serotonergic systems. Terminates the action of serotonin and recycles it in a sodium-dependent manner.

| Key Mechanism Factor 2 | |||||||||
| Factor Name | Monoamine oxidase | Structure Sequence | |||||||
| Protein Family | Flavin monoamine oxidase family | ||||||||
| Protein Function |
Catalyzes the oxidative deamination of primary and some secondary amine such as neurotransmitters, with concomitant reduction of oxygen to hydrogen peroxide and has important functions in the metabolism of neuroactive and vasoactive amines in the central nervous system and peripheral tissues (PubMed:20493079, PubMed:8316221, PubMed:18391214, PubMed:24169519). Preferentially oxidizes serotonin (PubMed:20493079, PubMed:24169519). Also catalyzes the oxidative deamination of kynuramine to 3-(2-aminophenyl)-3-oxopropanal that can spontaneously condense to 4-hydroxyquinoline (By similarity).

| Recommended Action | |||||||||
|---|---|---|---|---|---|---|---|---|---|
| Management | Meperidine and fentanyl should not be used with MAOIs or other agents that possess MAOI activity (e.g., furazolidone, linezolid, methylene blue, procarbazine). Some manufacturers of MAOIs also contraindicate the concomitant use of propoxyphene and methadone due to their possible serotonergic effects. At least 14 days should elapse between discontinuation of MAOI therapy and initiation of treatment with these opioids. Although morphine may also have significant CNS interactions with MAOIs, it is generally considered a safer alternative in patients treated with MAOIs who require a narcotic analgesic. | ||||||||
