Protein comprising truncated form of extracellular region protein of Frizzled 2, and pharmaceutical composition for treating bone diseases which comprises said protein
The present invention provides a protein comprising a truncated form of an extracellular region protein of Frizzled 2, which has higher secretion activity than that of a known protein comprising an extralellular cysteine-rich domain of Frizzled 2 in a production cell and bone mass-increasing activity higher than or equal to that of the known protein, or DNA encoding said protein.
