CC -!- FUNCTION: [Non-structural polyprotein p200]: Probable principal
CC replicase for the negative-strand DNA, which replicates the 40S (+)
CC genomic RNA into (-) antigenomic RNA. It cannot replicate the (-) into
CC (+) until cleaved into p150 and p90 mature proteins.
CC {ECO:0000250|UniProtKB:Q86500}.
CC -!- FUNCTION: [Protease/methyltransferase p150]: Protease that cleaves the
CC precursor polyprotein into two mature products. Together with RNA-
CC directed RNA polymerase p90, replicates the 40S genomic and antigenomic
CC RNA by recognizing replications specific signals. The heterodimer
CC P150/p90 is probably the principal replicase for positive-strand
CC genomic RNA and the 24S subgenomic RNA, which codes for structural
CC proteins. Responsible for the mRNA-capping of the viral mRNAs. This
CC function is necessary since all viral RNAs are synthesized in the
CC cytoplasm, and host capping enzymes are restricted to the nucleus.
CC Forms fibers late in the infection that may be involved in cell-to-cell
CC spread of the virus RNA in the absence of virus particle formation.
CC {ECO:0000250|UniProtKB:Q86500}.
CC -!- FUNCTION: [RNA-directed RNA polymerase p90]: Together with
CC protease/methyltransferase p150, replicates the 40S genomic and
CC antigenomic RNA by recognizing replications specific signals. The
CC heterodimer P150/p90 is probably the principal replicase for positive-
CC strand genomic RNA and the 24S subgenomic RNA, which codes for
CC structural proteins. A helicase activity is probably also present.
CC {ECO:0000250|UniProtKB:Q86500}.

CC also function efficiently with Cd(2+) and Co(2+). {ECO:0000255|PROSITE-
CC ProRule:PRU01237};
CC -!- SUBUNIT: [Protease/methyltransferase p150]: Interacts with RNA-directed
CC RNA polymerase p90. Interacts with host CALM1; this interaction is
CC necessary for the protease activity and viral infectivity. Interacts
CC with host C1QBP. Interacts with the capsid protein.
CC {ECO:0000250|UniProtKB:Q86500}.
CC -!- SUBUNIT: [RNA-directed RNA polymerase p90]: Interacts with human

CC {ECO:0000250|UniProtKB:Q86500}. Note=At 36 hpi, localizes to the host
CC cytoplasm, probably in vesicles inside host vacuoles of endosomal and
CC lysosomal origin (By similarity). At 72 hpi, localizes to filamentous
CC structures in the host cytoplasm (By similarity).
CC {ECO:0000250|UniProtKB:P13889, ECO:0000250|UniProtKB:Q86500}.
CC -!- SUBCELLULAR LOCATION: [RNA-directed RNA polymerase p90]: Host membrane
CC {ECO:0000250|UniProtKB:Q86500}. Host cytoplasm
CC {ECO:0000250|UniProtKB:Q86500}. Note=Localizes to the cytoplasm and to
CC the cytoplasmic fibers formed by protease/methyltransferase p150.
CC {ECO:0000250|UniProtKB:Q86500}.
CC -!- DOMAIN: [Protease/methyltransferase p150]: The N-terminus has a
CC methyltransferase activity for mRNA-capping. The C-terminus harbors a
CC protease active in cis or in trans which specifically cleaves and
CC releases the two mature proteins. Both the N-terminus and C-terminus
CC are required for fiber formation. The N-terminus is involved in
CC associating with membranes. An EF-hand Ca(2+)-binding motif is present
CC in the protease. Also contains 3 SH3-binding motifs that are
CC responsible for the interaction with host C1QBP.
CC {ECO:0000250|UniProtKB:Q86500}.
CC -!- PTM: [Non-structural polyprotein p200]: Specific enzymatic cleavage by
CC its own cysteine protease yield mature proteins p150 and p90.
CC {ECO:0000250|UniProtKB:Q86500}.
CC -!- MISCELLANEOUS: Rubella virus in utero infection has frequently severe
CC consequences on normal fetal development, collectively known as
CC congenital rubella syndrome (CRS). The teratogenicity of the virus is
CC possibly due to the interaction between the p90 protein and the human
CC RB1/retinoblastoma protein. {ECO:0000250|UniProtKB:Q86500}.
