Protein Domain : Carlavirus coat IPR013569

Type	Domain
Description	This domain is found together with the viral coat protein domain ( ) 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 [ ]. The complete coat protein (CP) sequences of 29 Indian Chrysanthemum virus B (CVB) isolates were highly heterogeneous, sharing nucleotide sequence identities of 74-98% [, ].
