Function
function
Sodium:iodide symporter that mediates the transport of iodide into the thyroid gland (PubMed:32084174, PubMed:8559252, PubMed:9341168).
Can also mediate the transport of chlorate, thiocynate, nitrate and selenocynate (PubMed:9341168).
Can also mediate the transport of chlorate, thiocynate, nitrate and selenocynate (PubMed:9341168).
Catalytic activity
- iodide(out) + 2 Na+(out) = iodide(in) + 2 Na+(in)
- chlorate(out) + 2 Na+(out) = chlorate(in) + 2 Na+(in)
- 2 Na+(out) + thiocyanate(out) = 2 Na+(in) + thiocyanate(in)
- 2 Na+(out) + nitrate(out) = 2 Na+(in) + nitrate(in)
- 2 Na+(out) + selenocyanate(out) = 2 Na+(in) + selenocyanate(in)
Activity regulation
Perchlorate inhibits iodide transport activity.
