Protein detail:
| Protein name | Fusion protein |
| Uniprot protein ID | P03420 |
| Protein length | 574 amino acids |
| Protein description | F protein is a class I fusion protein composed of 574 amino acids (AA). With a molecular weight of a 50 kDa C-terminal fragment F1 and a 20 kDa N-terminal fragment F2, the protein acquires a trimer of heterodimers. At AA positions 109 and 136, two furin cleavages take place. This feature releases a glycopeptide and thus reveals the hydrophobic site at F1 fragment. F1 and F2 are linked by a cysteine-rich region at two positions: between AA70 and AA212, and between AA37 and AA439. Other Frelated features involve N-glycosylation in F1 at AA position 500, and in F2 at AA positions 27 and 70. F protein is highly conserved, with only 25 AA differences between RSV subtypes A and B. |

| Evidence | Two independent selections resulted in viruses that each contained a unique point mutation, F488Y and T400A, that both conferred >1,000-fold-reduced susceptibility to VP-14637. |
