General annotation (Comments)

Function

Movement protein: transports viral genome to neighboring plant cells directly through plasmosdesmata, without any budding. The movement protein allows efficient cell to cell propagation, by bypassing the host cell wall barrier. Acts by forming a tubular structure at the host plasmodesmata, enlarging it enough to allow free passage of virion capsids By similarity.

Subcellular location

Movement protein: Host cell junctionhost plasmodesma By similarity. Note: Assembles in tubules that are embedded within modified plasmodesmata By similarity.

Large coat protein: Virion Potential.

Post-translational modification

Specific enzymatic cleavages by RNA1 encoded picornain 3C-like protease in vivo yield mature proteins By similarity.

Miscellaneous

The virus capsid is composed of 60 icosahedral units, each of which is composed of one copy each of the two coat proteins.

Sequence similarities

Belongs to the comoviridae genome polyprotein M family.

Caution

It is uncertain whether Met-1 or Met-103 is the initiator.
