S1 attaches the virion to the cell membrane by interacting with sialic acid-containing cell receptors, initiating the infection.
S2 is a class I viral fusion protein.
Under the current model, the protein has at least 3 conformational states: pre-fusion native state, pre-hairpin intermediate state, and post-fusion hairpin state.
During viral and target cell membrane fusion, the coiled coil regions (heptad repeats) assume a trimer-of-hairpins structure, positioning the fusion peptide in close proximity to the C-terminal region of the ectodomain.
The formation of this structure appears to drive apposition and subsequent fusion of viral and target cell membranes.
