By linking a peptide tag having the amino acid sequence X(PY)PZ to a protein of interest, and then expressing the protein, the protein of interest is efficiently accumulated in a soluble fraction, where P is proline; X is an amino acid sequence composed of 0 to 5 amino acids independently selected from R, G, S, K, T, L, N, Q, and M; Y is an amino acid sequence composed of 1 to 4 amino acids independently selected from R, G, K, T, L, N, Q, and M; q is an integer 1 to 10; and Z is an amino acid sequence composed of 0 to 10 amino acids independently selected from R, G, S, K, T, L, N, Q, and M; where the amino acid sequence of the peptide tag contains three or more Qs, Ms, Ls, Ns, and/or Ts in total.

Soluble expression of protein using peptide tag

A peptide comprising the sequence shown below is added as a peptide tag to a useful protein, followed by allowing its expression.X(PY)PZ In this formula, X, Y, and Z each represent an amino acid residue independently selected from the group consisting of R, G, S, K, T, L, N, Q, and H, with the proviso that at least one Y represents K, L, N, Q, H, or R. m represents an integer of 0 to 5; n represents 1, 2, or 3; q represents an integer of 1 to 10; and r represents an integer of 0 to 10.
