Function[SETD2_HUMAN] Histone methyltransferase that methylates 'Lys-36' of histone H3. H3 'Lys-36' methylation represents a specific tag for epigenetic transcriptional activation. Probably plays a role in chromatin structure modulation during elongation via its interaction with hyperphosphorylated POLR2A. Binds DNA at promoters. May also act as a transcription activator that binds to promoters. Binds to the promoters of adenovirus 12 E1A gene in case of infection, possibly leading to regulate its expression.[1] Publication Abstract from PubMedHuntington'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. Autoinhibitory structure of the WW domain of HYPB/SETD2 regulates its interaction with the proline-rich region of huntingtin.,Gao YG, Yang H, Zhao J, Jiang YJ, Hu HY Structure. 2014 Mar 4;22(3):378-86. doi: 10.1016/j.str.2013.12.005.
