PHF8 also known as Plant Homeodomains Finger Protein 8 is a histone demethylase enzyme. It specifically removes methyl groups from histone H3 at lysine 9 (H3K9me2/me1) and at lysine 27 (H3K27me2/me1). PHF8 is a protein with a molecular mass of around 109 kDa. This protein is expressed widely in various tissues appearing notably in brain tissues and the testis which suggests a broad physiological role.
Biological function summary

PHF8 plays an important role in the regulation of gene expression through chromatin remodeling. It forms part of transcriptional complexes and directly interacts with transcription factors and chromatin proteins. Its activity modulates gene silencing and activation processes impacting multiple cellular functions such as cell cycle progression and neurodevelopment. The activities controlled by PHF8 make it critical for maintaining normal cellular function.

Pathways

PHF8 takes part in integral signaling and epigenetic regulation pathways. It is involved in the MAPK/ERK signaling pathway which affects cell proliferation and differentiation. PHF8 also connects with other proteins such as p53 influencing pathways that govern cell growth and apoptosis. Through these interactions PHF8 helps maintain proper balance in cell cycle and development processes.

Mutations or dysregulation of PHF8 have links to developmental disorders and certain cancers. Specifically PHF8 mutations have associations with X-linked mental retardation and cleft lip/palate conditions. Dysregulated PHF8 activity interacts with proteins like p53 to influence cancer progression particularly in prostate cancer. Understanding PHF8's role aids in the exploration of therapeutic targets for these conditions.

General info

Function

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. Positively modulates transcription of histone demethylase KDM5C, acting synergistically with transcription factor ARX; synergy may be related to enrichment of histone H3K4me3 in regulatory elements.

Sequence similarities

Belongs to the JHDM1 histone demethylase family. JHDM1D subfamily.

Post-translational modifications

Phosphorylation at Ser-69 and Ser-120 are required for dissociation from chromatin and accumulation of H4K20Me1 levels during prophase.
