It is common to include a small segment of the viral hemagglutinin (HA) coat protein (typically with the amino acid sequence: YPYDVPDYA) in gene expression vectors as an epitope … WebJan 15, 2002 · We found that the pre-formed anaphase spindle of ΔTem1 spc34-3 cells broke into two relatively stable half spindles when cells were incubated at the restrictive temperature (Figure 8 B). This phenotype indicates that Spc34p helps to maintain the pole to pole MTs in anaphase, probably by stabilizing the spindle midzone.

Amino acid substitutions in the haemagglutinin (HA) gene can lead to the altered receptor-binding preference of the virus from a-2,3-linked to -2,6-linked sialic acid (Auewarakul et al., 2007; Stevens et al., 2006; Yamada et al., 2006). This would enable avian H5N1 viruses to recognize human-type host cell receptors and could

Influenza viruses initiate infection by binding to sialic acid of host glycans via viral surface protein hemagglutinin (HA). The receptor specificity varies by species, resulting in different host ranges. It is widely believed that human influenza viruses prefer glycans with terminal α2-6 sialic acid, while avian viruses ...
WebFeb 14, 2024 · Cleavage of hemagglutinin precursor (HA0) by cellular proteases results in the formation of two subunits, HA1 and HA2. The N-terminal fragment of HA2, named a fusion peptide (HAfp), possess a charged, amine N-terminus.
