The HCoV-HKU1 Spike/S1 protein plays a key role in infection by attaching viral particles to the host cell membrane, initiating the infection process. As a class I viral fusion protein, it promotes membrane fusion between virions and host cells through dynamic conformational transitions. HCoV-HKU1 Spike/S1 Protein (Q5MQD0, HEK293, His) is the recombinant Virus-derived HCoV-HKU1 Spike/S1 protein, expressed by HEK293 , with C-His labeled tag.
