Classification: C07K,C12P

Abstract:
A method of producing a 19P2 ligand or an amide thereof or a salt thereof, wherein the 19P2 ligand is bovine 19P2 ligand (SID NO:7), rat 19P2 ligand (SID NO:8), or human 19P2 ligand (SID NO:9) and wherein the method comprises(1) culturing a transformant harboring a vector containing a gene coding for a fusion protein or peptide comprising 19P2 ligand fused to a protein or a peptide having a cysteine residue at the N-terminus to express the fusion protein or peptide and(2) subjecting the fusion protein or peptide expressed to a reaction for cleavage of the peptide bond on the amino-terminal side of the cysteine residue.
