SARS-CoV-2 (2019nCoV, novel Coronavirus) Nucleocapsid protein (Coronavirus N protein)

About SARS-CoV-2 (2019nCoV, novel Coronavirus) Nucleocapsid protein (Coronavirus N protein) 1. SARS-CoV-2 (2019nCoV) N protein: Coronavirus N protein is required for coronavirus RNA synthesis, and has RNA chaperone activity that may be involved in template switch. Nucleocapsid protein is a most abundant protein of coronavirus. N protein packages the positive strand viral genome RNA into a helical […]

SARS-CoV-2 (2019nCoV, novel Coronavirus) membrane protein (Coronavirus M protein)

About SARS-CoV-2 (2019nCoV, novel Coronavirus) membrane protein (Coronavirus M protein) 1. SARS-CoV-2 (2019nCoV) M protein: Coronavirus M protein is believed to define the shape of the viral envelope,which contains three transmembrane domains. It has a small N-terminal glycosylated ectodomain and a much larger C-terminal endodomain that extends 6–8 nm into the viral particle. M protein usualy exists […]

SARS-CoV-2 (2019nCoV, novel Coronavirus) Envelop protein (Coronavirus E protein)

About SARS-CoV-2 (2019nCoV, novel Coronavirus) Envelop protein (Coronavirus E protein) 1. SARS-CoV-2 (2019nCoV) E protein: E protein is the smallest major structural proteins. It has a N-terminal ectodomain and a C-terminal endodomain with ion channel activity. During the replication cycle, E protein is abundantly expressed inside the infected cell, but only a small portion is incorporated into […]
