(EN) SARS-CoV-2 SPIKE PROTEIN VARIANT AND APPLICATION THEREOF
(FR) VARIANTE DE PROTÉINE SPIKE DU SARS-CoV-2 ET UTILISATION CORRESPONDANTE
(JA) SARS-CoV-2のSpikeタンパク質の変異体およびその用途
Abstract
(EN) Provided is a variant of a spike protein that can reduce the inducibility of an antibody that strengthens the ability of the spike protein of SARS-CoV-2 to bind to the angiotensin-converting enzyme 2. The variant of the SARS-CoV-2 spike protein according to the present invention is a protein formed from the amino acid sequence of (Sm) mentioned below. (Sm): an amino acid sequence from among (Sm1), (Sm2), or (Sm3) mentioned below. (Sm1): an amino acid sequence of the spike protein of wild-type SARS-CoV-2, the amino acid sequence having a mutation in an amino acid corresponding to at least one amino acid residue selected from the group consisting of the amino acids at the 30-position, 32-position, 64-position, 65-position, 66-position, 186-position, 187-position, 211-position, 213-position, 214-position, 216-position, and 217-position of the spike protein of standard SARS-CoV-2; (Sm2): the amino acid sequence of (Sm1), wherein there are 1 to 127 insertions, additions, substitutions, and/or deletions, and the mutated amino acid of (Sm1) is maintained; (Sm3): an amino acid sequence that is 90% or more identical to the amino acid sequence of (Sm1) and maintains the mutated amino acid of (Sm1).
(FR) L'invention concerne une variante d'une protéine spike qui peut réduire l'inductibilité d'un anticorps qui renforce la capacité de la protéine spike du SARS-CoV-2 à se lier à l'enzyme de conversion de l'angiotensine 2. La variante de la protéine spike du SARS-CoV-2 selon la présente invention est une protéine formée à partir de la séquence d'acides aminés de (Sm) mentionnée ci-dessous. (Sm) : une séquence d'acides aminés parmi (Sm1), (Sm2) ou (Sm3) mentionnée ci-dessous. (Sm1) : une séquence d'acides aminés de la protéine spike de SARS-CoV-2 de type sauvage, la séquence d'acides aminés ayant une mutation dans un acide aminé correspondant à au moins un résidu d'acide aminé choisi dans le groupe constitué par les acides aminés en positions 30, 32, 64, 65, 66, 186, 187, 211, 213, 214, 216 et 217 de la protéine spike du SARS-CoV-2 standard; (Sm2) : la séquence d'acides aminés de (Sm1), ayant de 1 à 127 insertions, additions, substitutions et/ou délétions, et l'acide aminé muté de (Sm1) étant maintenu; (Sm3) : une séquence d'acides aminés qui est identique à 90 % ou plus à la séquence d'acides aminés de (Sm1) et maintient l'acide aminé muté de (Sm1).
(JA) SARS-CoV-2のSpikeタンパク質のアンジオテンシン変換酵素2への結合能を増強する抗体の誘導能を低減しうるSpikeタンパク質の変異体を提供する。 本発明のSARS-CoV-2のSpikeタンパク質の変異体は、下記(Sm)のアミノ酸配列からなるタンパク質である: (Sm)下記(Sm1)、(Sm2)、または(Sm3)のアミノ酸配列: (Sm1)野生型SARS-CoV-2のSpikeタンパク質のアミノ酸配列において、基準SARS-CoV-2のSpikeタンパク質における、30位、32位、64位、65位、66位、186位、187位、211位、213位、214位、216位、および217位のアミノ酸からなる群から選択された少なくとも1つのアミノ酸残基と対応するアミノ酸に変異を有するアミノ酸配列; (Sm2)(Sm1)のアミノ酸配列において、1~127個の挿入、付加、置換および/または欠失を有し、かつ、(Sm1)の変異されたアミノ酸が維持されているアミノ酸配列; (Sm3)(Sm1)のアミノ酸配列に対して、90%以上の同一性を有し、かつ、(Sm1)の変異されたアミノ酸が維持されているアミノ酸配列。
