Rat skin calcium-binding protein is parvalbumin.
Only one major low-Mr calcium-binding protein could be isolated by h.p.l.c. procedures from aqueous extracts of homogenized adult rat skin. This was shown by tryptic peptide mapping and independent amino acid sequence analysis to be identical in all 109 residues with the parvalbumin from rat skeletal muscle. This calcium-binding protein was not in skin epidermis, but was confined to the dermal layer. Skin calcium-binding protein is therefore parvalbumin.
