【 摘 要 】

Skin Ca²⁺-binding protein (SCaBP) was reported to be distinct from the Ca²⁺-binding parvalbumin (PV), however, more recently its amino acid sequence was shown to be identical to PV. We purified a protein (M _r 12 000; pI4.5) from isolated epidermis (free of other cell layers) of adult rats and whole skin (containing no PV) of newborn rats. This protein is referred to as epidermal protein (EP-12), distinct from PV in its hydrophobicity, amino acid composition and immunological properties. Previously isolated SCaBP was shown to be a mixture of EP-12 and PV. The localization and possible functions of EP-12 and of PV in skin of adult and newborn rat are discussed.
