RN [1] RP NUCLEOTIDE SEQUENCE [GENOMIC RNA], AND PROTEIN SEQUENCE OF 357-381 AND RP 606-616. RX MEDLINE=93277375; PubMed=8503782; RA Hu J.S., Pang S.Z., Nagpala P.G., Siemieniak D.R., Slightom J.L., RA Gonsalves D.; RT "The coat protein genes of squash mosaic virus: cloning, sequence RT analysis, and expression in tobacco protoplasts."; RL Arch. Virol. 130:17-31(1993). CC -!- FUNCTION: The movement protein is assembled into tubules that CC allow the transport of virions from cell to cell. Binds to GTP and CC to single-stranded RNA and single-stranded DNA in a non-sequence- CC specific manner (By similarity). CC -!- SUBCELLULAR LOCATION: Cell junction; cell membrane; plasmodesma CC (By similarity). Viral movement proteins assembled in tubules are CC embedded within modified plasmodesmata (By similarity). CC -!- PTM: Specific enzymatic cleavages by RNA1 encoded picornain 3C- CC like protease in vivo yield mature proteins (By similarity). CC -!- PTM: The N-terminus of the 42 kDa coat protein is blocked. CC -!- MISCELLANEOUS: The virus capsid is composed of 60 icosahedral CC units, each of which is composed of one copy each of the two coat CC proteins. CC -!- SIMILARITY: Belongs to the comoviruses genome polyprotein M CC family.
