Vitamin D-binding protein is a multifunctional, highly expressed, polymorphic serum protein. These range from the transport of vitamin D metabolites to possible roles in the immune system and host defense. The molecular weight range, the time course of appearance, and the effect of dietary strontium all suggested that the newly appearing protein( band C) might represent the calcium-binding protein formed in response to vitamin D.

Using chromatographically purified calcium-binding protein from rat intestine, it was shown that this protein(band C) most probably is the calcium-binding protein. The major contaminating protein in the final purification of rat calcium-binding protein has also been identified on gels as the preexisting protein (band A), which is probably the precursor of the calcium-binding protein [1][2][3][4].
