Zusammenfassung:The present invention relates to novel epitopes of SARS-CoV2 causing coronavirus infection COVID-19, and to a use thereof. In designing a neutralization peptide protein capable of interfering with the binding between the spike protein S1-RBD present on the surface of the coronavirus and hACE2, from among the numerous charged amino acids present in the RBD structure, D420, R457, K458, E471, etc., which do not directly interact with hACE2, but exist behind the binding site, were discovered as novel epitopes on the RBD surface. It was confirmed that the novel RBD epitopes strongly interact with the neutralization peptide developed by the present inventors. La présente invention concerne de nouveaux épitopes de SARS-CoV2 provoquant une infection à coronavirus COVID-19 et leur utilisation. Dans la conception d'une protéine peptidique de neutralisation pouvant interférer avec la liaison entre la protéine de spicule S1-RBD présente sur la surface du coronavirus et de hACE2, parmi les nombreux acides aminés chargés présents dans la structure RBD, les éléments D420, R457, K458, E471, etc, qui n'interagissent pas directement avec hACE2, mais qui existent derrière le site de liaison, ont été découverts en tant que nouveaux épitopes sur la surface RBD. Il a été confirmé que les nouveaux épitopes RBD interagissent fortement avec le peptide de neutralisation développé par les présents inventeurs. 본 발명은 코로나바이러스 감염증 COVID-19를 일으키는 SARS-CoV2의 신규 에피토프 및 이의 용도에 관한 것으로서, 코로나 바이러스의 표면에 존재하는 스파이크(Spike) 단백질 S1-RBD와 hACE2 사이의 결합을 방해할 수 있는 중화 펩타이드(neutralization peptide) 단백질을 디자인함에 있어서, RBD 구조 속에 존재하는 수많은 전하를 띈 아미노산들 중에서도 hACE2와 직접 상호작용하지는 않지만, 결합부위 근처의 배후에 존재하는 D420, R457, K458, E471 등을 RBD 표면의 새로운 에피토프로 발굴하였다. 상기 신규 RBD 에피토프는 본 발명자들이 개발한 중화 펩타이드와 강하게 상호작용하는 것을 확인하였다.
