A protein epimorphine having the amino acid sequence represented by SEQ ID NO:1 in Sequence Listing which has an effect of inducing the differentiation of milk protein-producing cells of artiodactyls (cow, sheep, etc.) into a branched duct structure; and a gene encoding this protein. This epimorphine is usable as a drug or a modifying agent for artiodactyls. By using it, for example, cow or sheep mammary glands can be thickened and plugging in mammary glands can be prevented so that the yield of a desired protein secreted into the animal milk can be elevated.
