The protein differs from other coronaviruses, such as those that cause the common cold (bottom, from left: OC43, HKU1, NL63 and 229E). CREDIT Kelly Lab/Penn State Abstract: A tiny protein of SARS-CoV-2, the coronavirus that gives rise to COVID-19, may have big implications for future treatments, according to a team of Penn State researchers.
