UniProtKB description: Cysteine protease that cleaves a Gly-Gly dipeptide at its own C-terminus (By similarity). Required for aphid transmission and also has proteolytic activity (By similarity). Interacts with virions and aphid stylets (By similarity). Acts as a suppressor of RNA-mediated gene silencing, also known as post-transcriptional gene silencing (PTGS), a mechanism of plant viral defense that limits the accumulation of viral RNAs (By similarity). May have RNA-binding activity (By similarity).
