== Function ==
 +
[https://www.uniprot.org/uniprot/CAPSD_CARMV CAPSD_CARMV] 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).

== Publication Abstract from PubMed ==
 +
The structure of the Carnation Mottle Virus (CMtV) capsid protein has been determined at 3.2 A resolution by the method of molecular replacement. Three-dimensional data were collected from a small number of crystals (sp.g. I23, a = 382.6 A) using the synchrotron radiation with an image plate as detector. The coordinates of Tomato Bushy Stunt Virus (TBSV) were used as a searching model. Refinement of the coordinates of 7,479 non-hydrogen atoms performed by the program XPLOR, has led to an R-factor of 18.3%. It was found that the amino acid chain fold of capsid protein is very similar to that in other icosahedral viruses. However, there are some differences in the contact regions between protein subunits and also the lack of the beta-annulus around the 3-fold icosahedral axes. The structural and biochemical results lead us to consider an alternative assembly pathway.
