I found a really cool coronavirus illustration that led me to learn about viral attachment and entry. LEARN MORE ************** To learn more about this topic, start your googling with these keywords: Virus: a submicroscopic infectious agent that replicates only inside the living cells of an organism. The study of viruses is known as virology. Virion: a complete virus particle, and consists of nucleic acid surrounded by a protective coat of protein called a capsid. Coronaviruses: a group of related RNA viruses that cause diseases in mammals and birds. In humans and birds, they cause respiratory tract infections that can range from mild to lethal and include some cases of the common cold, SARS, MERS, and COVID-19. SARS-CoV-2: the virus that causes coronavirus disease 2019 (COVID-19), the respiratory illness responsible for the COVID-19 pandemic. Class I fusion proteins: resemble influenza virus hemagglutinin in their structure. Post-fusion, the active site has a trimer of α-helical coiled-coils Proteins featured in this video: - SARS-CoV-2 Spike (S) Protein - Heparan Sulfate Proteoglycan (HSPG) (Syndecan-4, especifically) - Angiotensin-converting enzyme 2 (ACE2) - Furin - Transmembrane protease, serine 2 (TMPRSS2) If you liked this week’s video, you might also like: Coronaviruses 101: Focus on Molecular Virology by Britt Glaunsinger Virology Lectures 2021: Attachment and entry by Vincent Racaniello Building a visual consensus model of the SARS-CoV-2 life cycle SUPPORT MINUTEEARTH ************************** If you like what we do, you can help us!: - Become our patron: - Share this video with your friends and family - Leave us a comment (we read them!)
