Gene Name SLC18A2
Uniprot ID VMAT2_HUMAN
KEGG Pathway hsa:6571
Protein Family Major facilitator superfamily
Protein Function
Involved in the ATP-dependent vesicular transport of biogenic amine neurotransmitters. Pumps cytosolic monoamines including dopamine, norepinephrine, serotonin, and histamine into synaptic vesicles (PubMed:23363473). Requisite for vesicular amine storage prior to secretion via exocytosis.

Gene Name CACNB1
Uniprot ID CACB1_HUMAN
KEGG Pathway hsa:782
Protein Family Calcium channel beta subunit family
Protein Function
Regulatory subunit of L-type calcium channels (PubMed:1309651, PubMed:8107964, PubMed:15615847). Regulates the activity of L-type calcium channels that contain CACNA1A as pore-forming subunit (By similarity). Regulates the activity of L-type calcium channels that contain CACNA1C as pore-forming subunit and increases the presence of the channel complex at the cell membrane (PubMed:15615847). Required for functional expression L-type calcium channels that contain CACNA1D as pore-forming subunit (PubMed:1309651). Regulates the activity of L-type calcium channels that contain CACNA1B as pore-forming subunit (PubMed:8107964).

      Mechanism Description
  • Additive hypotensive effects by the combination of Deserpidine and Nifedipine 

Recommended Action
      Management Hemodynamic responses should be monitored during coadministration, especially during the first few weeks of therapy. Patients should be advised to take the alpha-blocker at bedtime and to notify their physician if they experience dizziness or syncope while awake.
