TI  - Transcriptional repression by suppressor of hairless involves the binding of a 
      hairless-dCtBP complex in Drosophila.

AB  - Notch is the receptor for a conserved signaling pathway that regulates numerous 
      cell fate decisions during development [1]. Signal transduction involves the 
      presenilin-dependent intracellular processing of Notch and the nuclear 
      translocation of the intracellular domain of Notch, NICD [2-6]. NICD associates 
      with Suppressor of Hairless [Su(H)], a DNA binding protein, and Mastermind (Mam), 
      a transcriptional coactivator [7-9]. In the absence of Notch signaling, Su(H) 
      acts as a transcriptional repressor [10, 11]. Repression by Su(H) is relieved by 
      the activation of Notch [12-16]. In the Drosophila embryo, this transcriptional 
      switch from repression to activation is important for patterning the expression 
      of the single-minded (sim) gene along the dorsoventral axis [12]. Here, we 
      investigate the mechanisms by which Su(H) inhibits the expression of Notch target 
      genes in Drosophila. We show that Hairless, an antagonist of Notch signaling 
      [17-19], is required to repress the transcription of the sim gene. Hairless forms 
      a DNA-bound complex with Su(H). Furthermore, it directly binds the Drosophila 
      C-terminal Binding Protein (dCtBP), which acts as a transcriptional corepressor. 
      The dCtBP binding motif of Hairless is essential for the function of Hairless in 
      vivo. We propose that Hairless mediates transcriptional repression by Su(H) via 
      the recruitment of dCtBP.
