CC -!- FUNCTION: Movement protein that is involved in local cell-cell movement
CC via plamodesmata. At least five viral proteins, CP, CPm, p6, p64 and
CC Hsp70h are essential for cell-cell movement. Also plays a role in
CC virion formation. Together with Hsp70h and CPm, encapsidates the 5'-
CC terminal portion of the viral genome. {ECO:0000269|PubMed:17027895}.
CC -!- SUBCELLULAR LOCATION: Virion {ECO:0000269|PubMed:12551975}.
CC Note=Integral virion tail component. The N-terminus is exposed at the
CC virion surface, whereas the C-terminus is embedded in the virion.
