Protein

Capsid protein

Gene

ORF4

Organism
Carnation mottle virus (isolate China/Shanghai) (CarMV)
Status
Reviewed - Annotation score: 2 out of 5- Protein inferred from homologyi

Functioni

Capsid protein self-assembles to form an icosahedral capsid with a T=3 symmetry, about 32-35 nm in diameter, and consisting of 180 capsid proteins. Also 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).By similarity

Cofactori

Ca2+By similarityNote: Binds Ca(2+). Ca(2+) probably promotes virus assembly and stabilizes the virus particle.By similarity
