摘要:
In the present invention, GGTA1 (α1,3-galactosyltransferase), CMAH (CMP-N-acetylneuraminic acid hydroxylase), iGb3s (Isoglobotrihexosylceramide synthase) and β4GalNT2 (Beta-1,4-N-Acetyl-Galactosaminyl Transferase2) were removed. It relates to a pig and its use. The transgenic cloned pigs according to the present invention are removed by the CRISPR-Cas9 system, which is a gene shear, in which both loci of four genes, including GGTA1, CMAH, iGb3s and β4GalNT2, are removed, and acute and acute immunorejection occurring in xenotransplantation The response can be overcome, and it can be usefully used as a donor animal for xenotransplantation and cell transplantation.본 발명은 GGTA1(α1,3-galactosyltransferase), CMAH(CMP-N-acetylneuraminic acid hydroxylase), iGb3s(Isoglobotrihexosylceramide synthase) 및 β4GalNT2(Beta-1,4-N-Acetyl-Galactosaminyl Transferase2)가 제거된 형질전환 복제돼지 및 이의 용도에 관한 것이다. 본 발명에 따른 형질전환 복제돼지는 유전자 가위인 CRISPR-Cas9 시스템에 의해 GGTA1, CMAH, iGb3s 및 β4GalNT2 등 네 개 유전자의 두 좌위가 모두 제거되어 있으며, 이종장기이식에서 발생하는 초급성 및 급성 면역거부반응을 극복할 수 있는바, 이를 이종간 장기 및 세포 이식을 위한 공여 동물로서 유용하게 활용할 수 있다.
