Protein Domain : Luteovirus group 1 coat protein IPR001517

Type	Family
Description	Barley yellow dwarf virus (BYDV) can be separated into two groups based on serological relationships, presumably governed by the viral capsid structure [ ]. Coding regions of coat proteins have been identified for the MAV-PS1, P-PAV (group 1) and NY-RPV (group 2) isolates of BYDV. Group 1 proteins show 71% sequence similarity to each other, 51% similarity to those of group 2, and a high degree of similarity to those from other luteoviruses (including coat proteins from Beet western yellows virus (BWYV) [] and Potato leafroll virus (PLrV) [, ]).Among luteovirus coat protein sequences in general, several highly conserved domains can be identified, while other domains differentiate group 1 isolates from group 2 and other luteoviruses. Sequence comparisons between the genomes of PLrV, BWYV and BYDV have revealed ~65% protein sequence similarity between the capsid proteins of BWYV and PLrV and ~45% similarity between BYDV and PLrV [ ]. The N-terminal regions of these sequences, like those of many plant virus capsid proteins, is highly basic. These regions may be involved in protein-RNA interaction.
