Functional properties of the Na+/Ca2+ exchanger
| Transport mode | Bidirectional: Forward: Ca2+; Efflux Reverse: Ca2+ Influx |
| Coupling ratio | 3 Na+/1 Ca2+ or 4 Na+/1 Ca2+ |
| Reaction mechanism | Consecutive, Ca2+ first |
| Electrogenity | Na+ translocation is electrogenic. Ca2+ movement is electroneutral. |
| Gating properties | Voltage dependency |
