Protein attributes
| Sequence length | 860 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Involved in transcriptional regulation. Specifically recognizes and binds methylated 'Lys-9' of histone H3 (H3K9me) and promotes DNA methylation by recruiting DNMT3A to target CpG sites; these can be situated within the coding region of the gene. Mediates down-regulation of CDH1 expression. Ref.11 |
| Subunit structure | Homodimer. Interacts (via chromo domain) with histone H3K9me3. Has the highest affinity for H3K9me3, and lesser affinity for H3K9me2 and H3K9me1. Interacts with DNMT3, EHMT1 and SETDB1. Ref.11 Ref.14 Ref.16 |
| Subcellular location | Nucleus. Note: Detected on heterochromatin. Detected on nucleosomes. Ref.6 Ref.11 |
| Domain | The chromo domain mediates interaction with methylated 'Lys-9' of histone H3 (H3K9me), with the highest affinity for the trimethylated form (H3K9me3). Ref.14 Ref.16 |
| Post-translational modification | Phosphorylated in M (mitotic) phase. Ref.6 |
| Sequence similarities | Contains 4 ANK repeats. Contains 1 chromo domain. |
| Sequence caution | The sequence AAH46214.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended. The sequence BAB71284.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended. The sequence CAI46172.1 differs from that shown. Reason: Frameshift at positions 248, 255 and 731. |
