Abstract: The present invention relates to a nucleic acid molecule comprising the HpYPS1 gene encoding H. polymorpha yapsin1, a polypeptide encoded by the nucleic acid molecule, a H. polymorpha mutant strain having reduced yapsin activity by mutation of the HpYPS gene encoding H. polymorpha yapsin1, a recombinant H. polymorpha strain expressing a foreign protein produced by introducing a gene encoding the foreign protein into the H. polymorpha mutant strain, and a process for preparing a foreign protein comprising culturing the recombinant H. polymorpha strain under conditions to express the foreign protein and isolating the foreign protein from the culture.

Abstract: The present invention provides a human serum albumin-TIMP2 fusion protein having the amino acid sequence set forth in SEQ ID NO. 10, a polynucleotide encoding the same and a vector comprising the polynucleotide, a host cell transformed with the vector, a method for producing the human serum albumin-TIMP2 fusion protein and a pharmaceutical composition comprising the human serum albumin-TIMP2 fusion protein. The human serum albumin-TIMP2 fusion protein is stable and retains the activity of TIMP2, thus it can be used as a pharmaceutical composition to treat diseases related to angiogenesis and/or metastasis of cancer cells.
