The present invention concerns a protein comprising a mutated sequence of SEQ ID NO: 1, said mutated sequence of SEQ ID NO: 1 comprising at least one mutation A, A', B, C or C, in which: mutation A consists of substituting amino acids 43 to 52 of sequence SEQ ID NO: 1 with a sequence chosen from DFLAEGLTPR, KATN*ATLSPR and KATXATLSPR, mutation A' consists of substituting amino acids 47 to 52 of sequence SEQ ID NO: 1 with a sequence chosen from TSKLTR, FNDFTR, LSSMTR, PPSLTR and LSCGQR, mutation B consists of inserting a sequence chosen from DFLAEGLTPR, KATN*ATLSPR, KATXATLSPR, TSKLTR, FNDFTR, LSSMTR, PPSLTR and LSCGQR, between amino acids 52 and 53 of sequence SEQ ID NO: 1, mutation C consists of inserting a sequence chosen from DFLAEGLTPR, KATN*ATLSPR and KATXATLSPR, between amino acids 52 and 53 of sequence SEQ ID NO: 1, and of deleting amino acids 4 to 13 from sequence SEQ ID NO: 1, mutation C consists of inserting a sequence chosen from TSKLTR, FNDFTR, LSSMTR, PPSLTR and LSCGQR, between amino acids 52 and 53 of sequence SEQ ID NO: 1, and of deleting amino acids 4 to 9 from sequence SEQ ID NO: 1. |
