|---|---|---|---|---|---|---|
| additional information | alternative PE2 cleavage phenotypes observed in vertebrate and arthropod cells are due to differences in substrate specificity between the arthropod and vertebrate furin enzymes and not to differences in host cell glycoprotein processing pathways | Drosophila melanogaster | ? | - |
? |  |
| PE2 glycoprotein precursor + H2O | enzyme is involved in maturation of PE2 glycoprotein of alphaviruses. Enzyme cleaves efficiently PE2 glycoprotein mutants with residues arginine, serine, phenylalanine, histidine, asparagine, or aspartic acid at the +1 position | Drosophila melanogaster | ? | - |

| physiological function | expression of Dfurin1 enhances Sindbis virus titers in RPE.40 cells by a factor of 100-1000, and this increase correlates with efficient cleavage of PE2 glycoprotein | Drosophila melanogaster |
