Protein Structure
UniProt Annotation
Function Polycomb group (PcG) that specifically binds histone H3 trimethylated at 'Lys-36' (H3K36me3) and recruits the PRC2 complex. Probably involved in the transition from an active state to a repressed state in embryonic stem cells: acts by binding to H3K36me3, a mark for transcriptional activation, and recruiting H3K36me3 histone demethylases NO66 or KDM2B, leading to demethylation of H3K36 and recruitment of the PRC2 complex that mediates H3K27me3 methylation, followed by de novo silencing. Recruits the PRC2 complex to CpG islands and contributes to embryonic stem cell self-renewal. Also binds dimethylated at 'Lys- 36' (H3K36me2). Isoform 1 and isoform 2 inhibit transcription from an HSV-tk promoter. {ECO:0000269PubMed:15563832, ECO:0000269PubMed:21143197, ECO:0000269PubMed:23104054, ECO:0000269PubMed:23160351}.
Subcellular Localization Nucleus {ECO:0000269PubMed:15563832}.
Disease Associations
Tissue Specificity Isoform 1 is expressed in thymus, heart, lung and kidney. Isoform 2 is predominantly expressed in placenta, skeletal muscle and kidney, whereas isoform 1 is predominantly expressed in liver and peripheral blood leukocytes. Overexpressed in many types of cancers, including colon, skin, lung, rectal, cervical, uterus, liver cancers, in cell lines derived from different stages of melanoma and in glioma cell lines. {ECO:0000269PubMed:15563832}.
