Mechanism of action About 48% of serum calcium is ionic, ca 46% is bound to blood proteins, the rest is present as diffusible complexes, e.g., of citrate. The calcium ion level must be maintained within definite limits. Bones act as a reservoir of certain ions, in particular Ca2+ and...
Consistent with its status as a TRP channel, its alternative gene symbol is Trpp2. The mucolipins (Mcoln1, Mcoln2, and Mcoln3) are also in the TRP channel family. They are found mainly in endosomes, where they mediate release of Ca2+ into the cytoplasm, and are involved in the ...
