WATER-SOLUBLE MUTEIN OF FIBROBLAST GROWTH FACTOR (FGF) RECEPTOR

摘要

Disclosed are (1) a water-soluble mutein of an animal protein having activity as a receptor for a fibroblast growth factor (FGF) protein, (2) a recombinant DNA having a nucleotide sequence coding for the above water-soluble mutein, (3) a vector containing the above recombinant DNA, (4) a transformant transformed with the above vector, and (5) a process for producing the water-soluble mutein which comprises cultivating the above transformant in a culture medium, the mutein being useful as therapeutic agents or to enhance cell proliferation activity.
