ORF2b

Gene
ORF2b
Protein
Suppressor of silencing 2b
Organism
Tobacco streak virus (strain WC)
Length
205 amino acids
Function
Acts as 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. May directly interfere with the mobile silencing signal (By similarity).
Similarity
Belongs to the cucumovirus/ilarvirus protein 2b family.

Organism
Tomato aspermy virus
Length
95 amino acids
Function
Acts as 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. Forms a homodimer to measure siRNA duplex in a length-preference mode. Binds to both siRNA duplexes (19bp) and long siRNA duplexes (30bp).
Similarity
Belongs to the cucumovirus/ilarvirus protein 2b family.
