DESCRIPTION:TTG1-WDR proteins are scaffold proteins that aid the formation
  of transcription factor protein complexes. TTG1 is the most famous member
  of this WDR family in Arabidopsis thaliana\, and was isolated in this dep
 artment in 1999. Since then\, several groups have worked on this transcrip
 tion factor and thoroughly characterised its numerous functions. The ttg1 
 mutant shows numerous defects such as lack of anthocyanins\, lack of trich
 omes on the leaf blades\, increased number of root hairs and lack of pigme
 nts in the seeds. These diverse functions are delivered by the interaction
  of the TTG1 protein with MYB and bHLH transcription factors. Furthermore 
 the two closest relatives of TTG1 in Arabidopsis regulate circadian clock 
 by binding with TCP transcription factors to influence the expression of a
  central oscillator of the clock. We have investigated the surprising evol
 ution of these numerous diverse functions and have uncovered the central r
 ole of these proteins in circadian clock regulation.
