SETD2 protein is a histone methyltransferase that is specific for lysine-36 of histone H3, and methylation of this residue is associated with active chromatin. This protein also contains a novel transcriptional activation domain and has been found associated with hyperphosphorylated RNA polymerase II.[3]
Clinical significance
The SETD2 gene is located on the short arm of chromosome 3 and has been shown to play a tumour suppressor role in human cancer.[4]
Interactions
SETD2 has been shown to interact with Huntingtin.[5]Huntington's disease (HD), a neurodegenerative disorder characterized by loss of striatal neurons, is caused by an expansion of a polyglutamine tract in the HD protein huntingtin. SETD2 belongs to a class of huntingtin interacting proteins characterized by WW motifs.[3]
