CC   -!- FUNCTION: Transports viral genome to neighboring plant cells directly
CC       through plasmosdesmata, without any budding. The movement protein
CC       allows efficient cell to cell propagation, by bypassing the host cell
CC       wall barrier (Potential). Likely acts as a suppressor of RNA-mediated
CC       gene silencing, also known as post-transcriptional gene silencing
CC       (PTGS), a mechanism of plant viral defense that performs sequence-
CC       specific inhibition of viral mRNAs expression (By similarity).
CC       {ECO:0000250, ECO:0000305}.
