    Summary
    Enables RNA polymerase III type 3 promoter sequence-specific DNA binding activity. Predicted to be involved in RNA polymerase III preinitiation complex assembly. Part of transcription factor TFIIIB complex. Is expressed in several structures, including anterior endoderm; dorsal pharyngeal muscle primordium; embryonic/larval midgut; embryonic/larval midgut primordium; and larval muscle cell. Human ortholog(s) of this gene implicated in autosomal recessive nonsyndromic deafness 112. Orthologous to human BDP1 (BDP1 general transcription factor IIIB subunit).

    What's a GeneRIF?
    1. Assembly of SNAPc, Bdp1, and TBP on the U6 snRNA Gene Promoter in Drosophila melanogaster.
      Title: Assembly of SNAPc, Bdp1, and TBP on the U6 snRNA Gene Promoter in Drosophila melanogaster.
    2. Bdp1 recruitment requires that DmSNAPc be bound to a U6 PSE rather than a U1 PSE. This is consistent with the concept that DmSNAPc adopts different conformations on U6 and U1 PSEs, which lead to the subsequent recruitment of distinct general transcription factors and RNA polymerases for U6 and U1 gene transcription.
      Title: Bdp1 interacts with SNAPc bound to a U6, but not U1, snRNA gene promoter element to establish a stable protein-DNA complex.
    3. Results indicate that a portion of Brf1 is sandwiched between Bdp1 and TBP upstream of the U6 TATA box. Furthermore, Bdp1 traverses the DNA under the N-terminal stirrup of TBP to interact with the DNA (and very likely Brf1) downstream of the TATA sequence.
