Abstract:
The present invention provides a knock-in vector for producing a therapeutic protein comprises a 5′ end fragment containing 5176 bp promoter, exon 1, and 2 of bovine beta-casein genome DNA composed of polynucleotides having nucleic acid sequences of sequence number 1, as 5′ arm; a gene encoding the therapeutic protein; and exon 3 and 4 of bovine beta-casein genome DNA composed of polynucleotides having nucleic acid sequences written by sequence number 2, as 3′ arm.
Abstract:
The present invention relates to a knock-in vector that can target a complement regulatory protein (decay accelerating factor, DAF) gene and a human alpha 1,2-fucosyltransferase (HT) gene in a position of an alpha 1,3-galactosyl transferase (alpha 1,3-GT) gene, a cell transduced with the vector, a fertilized egg that is nuclear transplanted in the cell, a transgenic animal that is knocked out by the vector, and a method for producing the same. The knock-in vector of the present invention can be used to produce a transgenic animal in which hyperacute rejection that occurs in xeno-transplantation is controlled, so that the knock-in vector can be widely used for the production of a transgenic animal that can be used for effective xeno-transplantation.
