Gain of function 突变

WebSep 4, 2024 · Gain-of-function research is the serial passaging of microorganisms to increase transmissibility, virulence, immunogenicity, and host tropism. We use cookies to enhance your experience. WebBackground: Alterations of a genome can lead to changes in protein functions. Through these genetic mutations, a protein can lose its native function (loss-of-function, LoF), or it can confer a new function (gain-of-function, GoF). However, when a mutation occurs, it is difficult to determine whether it will result in a LoF or a GoF.
