Summary: Carlavirus coat
The Pfam group coordinates the annotation of Pfam families in Wikipedia, but we have not yet assigned a Wikipedia article to this family. If you think that a particular Wikipedia article provides good annotation, please let us know.
This tab holds the annotation information that is stored in the Pfam database. As we move to using Wikipedia as our main source of annotation, the contents of this tab will be gradually replaced by the Wikipedia tab.

InterPro entry IPR013569
This domain is found together with the viral coat protein domain (INTERPRO) in coat/capsid proteins of the plant infecting Carlavirus. It is required for genome encapsidation by forming ribonucleoprotein complexes along with TGB1 helicase and viral RNA. The N- and the C terminus of this coat protein can be exposed on the surface of the virus particle. The central core sequence may be important in maintaining correct tertiary structure of the coat protein and/or play a role in the interaction with the viral RNA. Coat proteins are often used to distinguish between Carlavirus isolates.
In the coat protein amino acid sequences of definitive and tentative species of carlaviruses, there is a region of seven amino acids (GLGVPTE) that are conserved [PUBMED:18192032]. The complete coat protein (CP) sequences of 29 Indian Chrysanthemum virus B (CVB) isolates were highly heterogeneous, sharing nucleotide sequence identities of 74-98% [PUBMED:17006596, PUBMED:16279199].

We make a range of alignments for each Pfam-A family:
- the curated alignment from which the HMM for the family is built
- the alignment generated by searching the sequence database using the HMM
- Representative Proteomes (RPs) at 15%, 35%, 55% and 75% co-membership thresholds
- alignment generated by searching the NCBI sequence database using the family HMM
- alignment generated by searching the metagenomics sequence database using the family HMM
You can see the alignments as HTML or in three different sequence viewers:
- Pfam viewer
- an HTML-based viewer that uses DAS to retrieve alignment fragments on request
