CRYSTAL STRUCTURE OF MS2 COAT PROTEIN DIMERCRYSTAL STRUCTURE OF MS2 COAT PROTEIN DIMER

Structural highlights

1msc is a 1 chain structure with sequence from Escherichia phage MS2. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Method:X-ray diffraction, Resolution 2Å
Resources:FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

Function

CAPSD_BPMS2 Self-assembles to form the T=3 icosahedral virus shell that protects the viral nucleic acid. Acts as a translational repressor by binding with high specificity to a single stem-loop structure in the genomic RNA that contains the initiation codon of the gene for the viral replicase. Involved in virus assembly through the interaction between a capsid protein dimer and the multiple packaging signals present in the RNA genome.[1] [2] [3] [4] [5] [6]

Evolutionary Conservation

Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf.
