• PubMed Abstract: 
  

  Tubby-like proteins (TULPs) are found in a broad range of multicellular organisms. In mammals, genetic mutation of tubby or other TULPs can result in one or more of three disease phenotypes: obesity (from which the name "tubby" is derived), retinal degeneration, and hearing loss. These disease phenotypes indicate a vital role for tubby proteins; however, no biochemical function has yet been ascribed to any member of this protein family. A structure-directed approach was employed to investigate the biological function of these proteins. The crystal structure of the core domain from mouse tubby was determined at a resolution of 1.9 angstroms. From primarily structural clues, experiments were devised, the results of which suggest that TULPs are a unique family of bipartite transcription factors.
