Figure 1

Schematic representation of putative structure and mutation map of human metapneumovirus F protein. SS = signal sequence; FP = fusion peptide; HRA = heptad repeat A; HRB = heptad repeat B; TM = transmembrane domain; and CT = cytoplasmic tail. Arrow indicates cleavage site; arrowheads indicate putative N-glycosylation sites. Amino acid variations are indicated by asterisks, with the number of asterisks representing the number of distinct strains in which the variation was found.
