HCoV-HKU1 Spike/S1 Protein (Q5MQD0, HEK293, His)

The HCoV-HKU1 Spike/S1 Protein plays a pivotal role in infection by attaching the virion to the host cell membrane, initiating the infection process. As a class I viral fusion protein, it facilitates membrane fusion between the virion and host cell through dynamic conformational transitions. The coiled coil regions, with heptad repeats, form a trimer-of-hairpins structure during fusion, bringing the fusion peptide close to the C-terminal region and driving the fusion of viral and target cell membranes. 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. The total length of HCoV-HKU1 Spike/S1 Protein (Q5MQD0, HEK293, His) is 760 a.a., with molecular weight of 130-140 KDa.

130-140 kDa.
