We apologize for Proteopedia being slow to respond. For the past two years, a new implementation of Proteopedia has been being built. Soon, it will replace this 18-year old system. All existing content will be moved to the new system at a date that will be announced here.

| - | + | [https://www.uniprot.org/uniprot/TUBR_BACTI TUBR_BACTI] A DNA-binding protein that is part of the type III plasmid partition system used to ensure correct segregation of the pBtoxis plasmid. Cooperatively binds to the centromere-like site (tubC), which may seed filament formation by the TubZ polymerizing GTPase, stabilizing TubZ filaments. TubR-tubC complexes track the depolymerizing minus end of the filament, probably pulling plasmid within the cell (PubMed:20534443, PubMed:23010931, PubMed:25825718). Required for plasmid replication (PubMed:16936050, PubMed:17873046). Negatively regulates levels of TubZ; its effect on RNA expression has not been shown (Probable). Specifically binds iterons, 12-bp imperfect direct repeats that function as a plasmid origin of replication (PubMed:17873046, PubMed:23010931, PubMed:25825718). Four TubR dimers bind to tubC, forming an extended bent DNA-protein filament with protein wrapping helically around the outside of the DNA (PubMed:20534443, PubMed:23010931).<ref>PMID:16936050</ref> <ref>PMID:17873046</ref> <ref>PMID:20534443</ref> <ref>PMID:23010931</ref> <ref>PMID:25825718</ref> <ref>PMID:17510284</ref> | |
