Specific Activity: 0.064 pmol/min/μg
Assay conditions: PHF8 enzyme is incubated with biotinylated histone H3 peptide substrate in HEPES-based buffer in a 10 µg reaction for 1 hr. at RT. Add 5 µg of AlphaLISA™ anti-Rabbit Acceptor beads (20 µg/ml), followed by addition of 5 µl of antibody and 30 min. incubation at RT. Add 10 µg of AlphaScreen™ Streptavidin-conjugated donor beads (40 µg/ml). Alpha counts are measured after 10 min. RT incubation.
精製度>= 95 % SDS-PAGE.

- Histone lysine demethylase PHF8
- Jumonji C domain containing histone demethylase 1F
機能Histone lysine demethylase with selectivity for the di-and monomethyl states that plays a key role cell cycle progression, rDNA transcription and brain development. Demethylates mono- and dimethylated histone H3 'Lys-9' residue (H3K9Me1 and H3K9Me2), dimethylated H3 'Lys-27' (H3K27Me2) and monomethylated histone H4 'Lys-20' residue (H4K20Me1). Acts as a transcription activator as H3K9Me1, H3K9Me2, H3K27Me2 and H4K20Me1 are epigenetic repressive marks. Involved in cell cycle progression by being required to control G1-S transition. Acts as a coactivator of rDNA transcription, by activating polymerase I (pol I) mediated transcription of rRNA genes. Required for brain development, probably by regulating expression of neuron-specific genes. Only has activity toward H4K20Me1 when nucleosome is used as a substrate and when not histone octamer is used as substrate. May also have weak activity toward dimethylated H3 'Lys-36' (H3K36Me2), however, the relevance of this result remains unsure in vivo. Specifically binds trimethylated 'Lys-4' of histone H3 (H3K4me3), affecting histone demethylase specificity: has weak activity toward H3K9Me2 in absence of H3K4me3, while it has high activity toward H3K9me2 when binding H3K4me3.
関連疾患Defects in PHF8 are the cause of mental retardation syndromic X-linked Siderius type (MRXSSD) [MIM:300263]. A disorder characterized by mild to borderline mental retardation with or without cleft lip/cleft palate.
配列類似性Belongs to the JHDM1 histone demethylase family. JHDM1D subfamily.
Contains 1 JmjC domain.
Contains 1 PHD-type zinc finger.
ドメインThe PHD-type zinc finger mediates the binding to H3K4me3. Binding to H3K4me3 promotes its access to H3K9me2.
The linker region is a critical determinant of demethylase specificity. It enables the active site of JmjC to reach the target H3K9me2 when the PHD-type zinc finger binds to H3K4me3.
翻訳後修飾Phosphorylation at Ser-69 and Ser-120 are required for dissociation from chromatin and accumulation of H4K20Me1 levels during prophase.
細胞内局在Nucleus. Nucleus > nucleolus. Recruited to H3K4me3 sites on chromatin during interphase. Dissociates from chromatin when cells enter mitosis.
