Protein containing truncated form of Frizzled2 extracellular region protein, and pharmaceutical composition for treatment of bone disease containing the 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.
