CO-CRYSTAL STRUCTURE OF XENOPUS TFIIIA ZINC FINGER DOMAIN BOUND TO THE 5S RIBOSOMAL RNA GENE INTERNAL CONTROL REGION

Structural highlights

1tf6 is a 6 chain structure with sequence from African clawed frog. The March 2007 RCSB PDB Molecule of the Month feature on Zinc Fingers by David S. Goodsell is 10.2210/rcsb_pdb/mom_2007_3. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.

Function

[TF3A_XENLA] Acts as both a positive transcription factor for 5S RNA genes and a specific RNA binding protein that complexes with 5S RNA in oocytes to form the 7S ribonucleoprotein storage particle. May play an essential role in the developmental change in 5S RNA gene expression. Interacts with the internal control region (ICR) of approximately 50 bases within the 5S RNA genes, is required for correct transcription of these genes by RNA polymerase III. Also binds the transcribed 5S RNA's.

Evolutionary Conservation

Publication Abstract from PubMed

The crystal structure of the six NH2-terminal zinc fingers of Xenopus laevis transcription factor IIIA (TFIIIA) bound with 31 bp of the 5S rRNA gene promoter has been determined at 3.1 A resolution. Individual zinc fingers are positioned differently in the major groove and across the minor groove of DNA to span the entire length of the duplex. These results show how TFIIIA can recognize several separated DNA sequences by using fewer fingers than necessary for continuous winding in the major groove.
