Abstract:
1. A fusion protein comprising: a) a somatostatin receptor polypeptide, the somatostatin receptor polypeptide being truncated at its C-terminus relative to wild-type somatostatin receptor; and b) a heterologous polypeptide fused to the N-terminus, if not truncated, or the trucated N-terminus, if truncated, or truncated C-terminus of said somatostatin receptor polypeptide: wherein: i) the C-terminus of said somatostatin receptor polypeptide is truncated at amino acid ii) the somatostatin receptor polypeptide is also truncated at its N-terminus; iii) the fusion protein comprises a leader sequence fused to the truncated C-terminus of said somatostatin receptor polypeptide; iv) the heterologous polypeptide is a protein fusion tag that is hemagglutinin A or has enzymatic activity; or v) the fusion protein comprises a leader sequence that is an IgK leader sequence.
