General annotation (Comments)
| Function | Regulator of histone methyltransferase complexes that plays an essential role in embryonic development, including heart and liver development, neural tube fusion process and hematopoiesis. Acts by modulating histone methyltransferase activity and promoting the recruitment of histone methyltransferase complexes to their target genes. Binds DNA and mediates the recruitment of the PRC2 complex to target genes in embryonic stem cells. Does not have histone demethylase activity but regulates activity of various histone methyltransferase complexes. In embryonic stem cells, it associates with the PRC2 complex and inhibits trimethylation of 'Lys-27' of histone H3 (H3K27me3) by the PRC2 complex, thereby playing a key role in differentiation of embryonic stem cells and normal development. In cardiac cells, it is required to repress expression of cyclin-D1 (CCND1) by activating methylation of 'Lys-9' of histone H3 (H3K9me) by the GLP1/EHMT1 and G9a/EHMT2 histone methyltransferases. Also acts as a transcriptional repressor of ANF via its interaction with GATA4 and NKX2-5. Participates in the negative regulation of cell proliferation signaling. Ref.7 |
| Subunit structure | Associates with a histone methyltransferase complex containing GLP1/EHMT1 and G9a/EHMT2. Interacts with SUZ12; the interaction is direct. Interacts with GATA4 (via the N-terminal region). Interacts with NKX2-5 (via the C-terminal region). Interacts with RB1. Interacts with ZNF496 By similarity. Associates with the PRC2 complex, which includes EED, EZH1, EZH2, SUZ12, RBBP4 and AEBP2; JARID2 is probably not a core component of the PRC2 complex and associates to PRC2 via its interaction with SUZ12. |
| Subcellular location | Nucleus. Note: Colocalizes with the PRC2 complex on chromatin. Ref.7 |
| Tissue specificity | During embryogenesis, predominantly expressed in neurons and particularly in dorsal root ganglion cells. |
| Domain | The ARID domain is required to target the PRC2 complex to its target genes By similarity. The GSGFP motif is required for the interaction with SUZ12 By similarity. |
| Sequence similarities | Contains 1 ARID domain. Contains 1 JmjC domain. Contains 1 JmjN domain. |
| Sequence caution | The sequence AAC50822.1 differs from that shown. Reason: Frameshift at position 1233. |

| This entry describes 2 isoforms produced by alternative splicing. [Align] [Select] | ||||||
| Isoform 1 (identifier: Q92833-1) This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry. | ||||||
| Isoform 2 (identifier: Q92833-2) The sequence of this isoform differs from the canonical sequence as follows: 1-60: MSKERPKRNI...GIAGSLKTVN → MAAPRVCQVQFLVAYLEEPGIE 949-1246: WYCIPAEEEN...SSSKSASSSS → CLSVEPVFPH...AWRGVLGPRL | ||||||
