Protein Family Sodium:neurotransmitter symporter (SNF) (TC 2.A.22) family
Protein Function
Amine transporter (PubMed:1406597, PubMed:8302271, PubMed:15505207). Terminates the action of dopamine by its high affinity sodium-dependent reuptake into presynaptic terminals (By similarity). Regulator of light-dependent retinal hyaloid vessel regression, downstream of OPN5 signaling (By similarity).

      Mechanism Description
  • Antagonize the effect of Dexmethylphenidate when combined with Methdilazine 

Recommended Action
      Management Amphetamine, amphetamine derivatives, and other CNS stimulants should generally not be used, particularly for weight reduction, in patients treated with phenothiazines.
