    Huntington's disease (HD) is an autosomally dominant neurodegenerative disorder caused by expansion of polyglutamine (polyQ) in the huntingtin (Htt) protein. Htt yeast two-hybrid protein B (HYPB/SETD2), a histone methyltransferase, directly interacts with Htt and is involved in HD pathology. Using NMR techniques, we characterized a polyproline (polyP) stretch at the C terminus of HYPB, which directly interacts with the following WW domain and leads this domain predominantly to be in a closed conformational state. The solution structure shows that the polyP stretch extends from the back and binds to the WW core domain in a typical binding mode. This autoinhibitory structure regulates interaction between the WW domain of HYPB and the proline-rich region (PRR) of Htt, as evidenced by NMR and immunofluorescence techniques. This work provides structural and mechanistic insights into the intramolecular regulation of the WW domain in Htt-interacting partners and will be helpful for understanding the pathology of HD.
