Claim:
1. A fusion protein that can be expressed as a soluble protein, comprising: (1) a first amino acid sequence comprising the amino acid sequence of a polypeptide that is represented by the formula (Z) wherein n represents an integer from 1 to 5 and Z represents polypeptide selected from the group of: and that has the capacity when expressed as a fusion protein with a target protein to render said fusion protein expressible as a soluble protein; and (2) a second amino acid sequence comprising the amino acid sequence of a target protein, wherein the fusion protein further comprises, on the amino terminal side of the first amino acid sequence, an amino acid sequence that facilitates purification, and; wherein the expression of the fusion protein comprising the amino acid sequence that facilitates purification, an amino acid sequence of the polypeptide that is represented by the formula (Z) wherein the amino acid sequence that facilitates the purification is a histidine tag sequence; and wherein the target protein is at least one selected from the group of apoaequorin,
