Fig. 4From: Sequencing of emerging canine distemper virus strain reveals new distinct genetic lineage in the United States associated with disease in wildlife and domestic canine populationsAlternate start sites for fusion (F) gene. The new strain (top two sequences) has a predicted start site 75 bp preceding that for America-2 A75/17 and Onderstepoort and 27 bp from Asia-2. This adds 25 and 9 amino acids, respectively, to the signal peptide region of the proteinBack to article page
