Predicted gene boundaries, cis-acting gene-start and gene-end signals, and intergenic regions of hMPV isolates. The alignments show the N-P, P-M, M-F, F-M2, M2-SH, SH-G, and G boundaries. Conserved sequence motifs at the end and beginning of each gene are indicated by bold uppercase letters, and a consensus sequence is given below. Translational stop and start codons are underlined.
