The fusion glycoprotein precursor of Newcastle disease virus is ubiquitously cleaved in the constitutive secretory pathway if it possesses an oligobasic cleavage motif (RRQR/KR), whereas the precursor is refractory to cleavage if the motif is monobasic (GR/KQGR). We examined the cleavage activity of the mammalian subtilisin-related proteinases furin/PACE, PC2, and PC1/PC3, which are thought to be responsible for proprotein processing in either the constitutive (furin/PACE) or the regulated (PC2 and PC1/PC3) secretory pathway, for the viral precursors with different cleavage motifs. Only furin/PACE was fully capable of cleaving the precursors with the oligobasic motif. PC2 and PC1/PC3 were incapable or only partially capable of cleaving at this motif. None of the proteinases cleaved the monobasic motif. These results suggest involvement of furin/PACE in viral protein processing in the constitutive secretory pathway.
