Gene : PBRP A. thaliana

DB identifier  ? AT4G36650 Secondary Identifier  ? locus:2115255
Name  ? plant-specific TFIIB-related protein Brief Description  plant-specific TFIIB-related protein
TAIR Computational Description  plant-specific TFIIB-related protein;(source:Araport11)
TAIR Curator Summary  Encodes a protein with similarity to the general transcription factor TFIIB. pBRP binds rDNA sequences in vitro. pBRP has been localized to the outer face of the plastid membrane with GFP fusion however, under conditions of proteosome inhibition it is found in the nucleus.
TAIR Short Description  plant-specific TFIIB-related protein
TAIR Aliases  ATPBRP, PBRP

Type Comment Proteins
PBRP1_ARATH function Plant-specific TFIIB-related protein that may be involved in an intracellular signaling pathway between plastids and the nucleus (PubMed:12697827). May act as general transcription factor (GTF) of RNA polymerase I-dependent transcription and rRNA synthesis. Forms a ternary complex with TBP2 and the rDNA promoter region (PubMed:18668124).
PBRP1_ARATH subcellular location Localizes to the nucleus under conditions of proteasome inhibition.
PBRP1_ARATH tissue specificity Widely expressed.
