General annotation (Comments)
| Function | Histone demethylase that demethylates 'Lys-4' of histone H3, thereby playing a central role in histone code. Does not demethylate histone H3 'Lys-9' or H3 'Lys-27'. Demethylates trimethylated, dimethylated and monomethylated H3 'Lys-4'. Acts as a transcriptional corepressor for FOXG1B and PAX9. Favors the proliferation of breast cancer cells by repressing tumor suppressor genes such as BRCA1 and HOXA5. In contrast, may act as a tumor suppressor for melanoma. Ref.6 Ref.8 Ref.9 Ref.12 |
| Cofactor | Binds 1 Fe2+ ion per subunit By similarity. |
| Subunit structure | Interacts with FOXG1B, PAX9, MYC, MYCN and RB1. Interacts with HDAC1, HDAC4, HDAC5 and HDAC7 By similarity. Ref.6 Ref.7 Ref.8 Ref.10 Ref.11 |
| Subcellular location | |
| Tissue specificity | Ubiquitously expressed, with highest levels in testis. Down-regulated in melanoma and glioblastoma. Up-regulated in breast cancer (at protein level). Ref.1 Ref.2 Ref.3 Ref.5 Ref.7 |
| Domain | Both the JmjC domain and the JmjN domain are required for enzymatic activity. The 2 first PHD-type zinc finger domains are required for transcription repression activity. |
| Sequence similarities | Belongs to the JARID1 histone demethylase family. Contains 1 ARID domain. Contains 1 JmjC domain. Contains 1 JmjN domain. Contains 3 PHD-type zinc fingers. |
| Sequence caution | The sequence CAB63108.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally shortened. |
