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. |
