Description
Technical field
The present invention relates to DNA recombinant technology and pharmaceutical field.More specifically, the present invention relates to the fusion rotein of people's prokinin the 5th structural domain (Kininogen D5) and apoptosis induction ligand related to human tumor necrosis factor (hereinafter to be referred as TRAIL), the encode dna sequence dna of this fusion rotein, the carrier that contains this dna sequence dna, the host cell that contains this carrier, prepare the method for this fusion rotein with genetically engineered, and this fusion rotein is as the application in the disease treatments such as tumour.
Background technology
Prokinin (Kininogen) is found existing so far recent two decades, and its major function is an anticoagulation, so all play a significant role in fibrinolytic, thrombus disease, inflammation etc.People's prokinin is made up of 644 amino acid, aminoacid sequence is seen GenBank No.:ABB59550, the product of its coded by said gene is under the effect of kallikrein, excise one of them structural region (being D4), remaining D1,2,3 and D5,6 connect into prokinin (being Kininogen) by a disulfide linkage, nucleotide sequence is seen GenBank No.:AH005302.In recent years find that it has antineoplastic action (mainly concentrating on Kininogen D5 part), protein [Blood, 2000 that the N-that has proved prokinin holds 402-626 amino acids (being the 24-248 amino acids of Kininogen D5) or partial sequence wherein to form; 95 (2): 543-550], or polypeptide [Arterioscler Thromb Vasc Biol, 2001; 21 (9): 1427-1433] propagation that can be by suppressing endotheliocyte, move and induce its apoptosis and produce the tumor neovasculature effect that suppresses in vivo, thereby have anti-tumor function.
Nineteen ninety-five, external report is expressed sequence label library (expressed sequence tag from the people, EST) screen a kind of gene of the anti-tumor protein matter of encoding in, the protein of this genes encoding is called tumor necrosin relative death inducing ligand (tumor necrosis factor-related apoptosis-inducing ligand, TRAIL), claim Tumor wilting extract (apoptotin-2 ligand again, be called for short Apo-2L), be tumour necrosis factor (tumor necrosisfactor, TNF) one of family member, it is by starting cell inherent apoptosis program, induced tumor and transformant apoptosis effectively, and normal cell is not had influence.The code sequence of people's trail dna is shown 843 Nucleotide (SEQ ID NO.3), and nucleotide sequence is seen GenBank No.:NM_003810, and encoded protein matter TRAIL forms (SEQ ID NO.4) by 281 amino acid.Proved already that TRAIL was typical II type transmembrane protein, its N-holds the extracellular region of the 95th or 114 beginning can form free solubility tumor apoptosis fibroin, has the tumor death effect equally.This gene can obtain from biotech company (http://www.invivogen.com) at present.
