Chain A   (PHF8_HUMAN | Q9UPP1)
molecular function
    GO:0003682    chromatin binding    Interacting selectively and non-covalently with chromatin, the network of fibers of DNA, protein, and sometimes RNA, that make up the chromosomes of the eukaryotic nucleus during interphase.
    GO:0051213    dioxygenase activity    Catalysis of an oxidation-reduction (redox) reaction in which both atoms of oxygen from one molecule of O2 are incorporated into the (reduced) product(s) of the reaction. The two atoms of oxygen may be distributed between two different products.
    GO:0032452    histone demethylase activity    Catalysis of the removal of a methyl group from a histone.
    GO:0071558    histone demethylase activity (H3-K27 specific)    Catalysis of the removal of a methyl group from lysine at position 27 of the histone H3 protein.
    GO:0051864    histone demethylase activity (H3-K36 specific)    Catalysis of the reaction: histone H3 N6-methyl-L-lysine (position 36) + alpha-ketoglutarate + O2 = succinate + CO2 + formaldehyde + lysine. This reaction is the removal of a methyl group from lysine at position 36 of the histone H3 protein.
    GO:0032454    histone demethylase activity (H3-K9 specific)    Catalysis of the reaction: histone H3 N6-methyl-L-lysine (position 9) + alpha-ketoglutarate + O2 = succinate + CO2 + formaldehyde + lysine. This reaction is the removal of a methyl group from lysine at position 9 of the histone H3 protein.
    GO:0035575    histone demethylase activity (H4-K20 specific)    Catalysis of the reaction: histone H4 N6-methyl-L-lysine (position 20) + 2-oxoglutarate + O2 = histone H4 L-lysine (position 20) + succinate + formaldehyde + CO2. This reaction is the removal of a methyl group from lysine at position 20 of the histone H4 protein.
    GO:0005506    iron ion binding    Interacting selectively and non-covalently with iron (Fe) ions.
    GO:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
    GO:0035064    methylated histone binding    Interacting selectively and non-covalently with a histone in which a residue has been modified by methylation. Histones are any of a group of water-soluble proteins found in association with the DNA of eukaroytic chromosomes.
    GO:0016491    oxidoreductase activity    Catalysis of an oxidation-reduction (redox) reaction, a reversible chemical reaction in which the oxidation state of an atom or atoms within a molecule is altered. One substrate acts as a hydrogen or electron donor and becomes oxidized, while the other acts as hydrogen or electron acceptor and becomes reduced.
    GO:0016706    oxidoreductase activity, acting on paired donors, with incorporation or reduction of molecular oxygen, 2-oxoglutarate as one donor, and incorporation of one atom each of oxygen into both donors    Catalysis of the reaction: A + 2-oxoglutarate + O2 = B + succinate + CO2. This is an oxidation-reduction (redox) reaction in which hydrogen or electrons are transferred from 2-oxoglutarate and one other donor, and one atom of oxygen is incorporated into each donor.
    GO:0005515    protein binding    Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
    GO:0008270    zinc ion binding    Interacting selectively and non-covalently with zinc (Zn) ions.
biological process
    GO:0000082    G1/S transition of mitotic cell cycle    The mitotic cell cycle transition by which a cell in G1 commits to S phase. The process begins with the build up of G1 cyclin-dependent kinase (G1 CDK), resulting in the activation of transcription of G1 cyclins. The process ends with the positive feedback of the G1 cyclins on the G1 CDK which commits the cell to S phase, in which DNA replication is initiated.
    GO:0007420    brain development    The process whose specific outcome is the progression of the brain over time, from its formation to the mature structure. Brain development begins with patterning events in the neural tube and ends with the mature structure that is the center of thought and emotion. The brain is responsible for the coordination and control of bodily activities and the interpretation of information from the senses (sight, hearing, smell, etc.).
    GO:0007049    cell cycle    The progression of biochemical and morphological phases and events that occur in a cell during successive cell replication or nuclear replication events. Canonically, the cell cycle comprises the replication and segregation of genetic material followed by the division of the cell, but in endocycles or syncytial cells nuclear replication or nuclear division may not be followed by cell division.
    GO:0071557    histone H3-K27 demethylation    The modification of histone H3 by the removal of a methyl group from lysine at position 27 of the histone.
    GO:0070544    histone H3-K36 demethylation    The modification of histone H3 by the removal of a methyl group from lysine at position 36 of the histone.
    GO:0033169    histone H3-K9 demethylation    The modification of histone H3 by the removal of a methyl group from lysine at position 9 of the histone.
    GO:0035574    histone H4-K20 demethylation    The modification of histone H4 by the removal of a methyl group from lysine at position 20 of the histone.
    GO:0061188    negative regulation of chromatin silencing at rDNA    Any process that decreases the rate, frequency, or extent of the repression of transcription of ribosomal DNA by altering the structure of chromatin.
    GO:0055114    oxidation-reduction process    A metabolic process that results in the removal or addition of one or more electrons to or from a substance, with or without the concomitant removal or addition of a proton or protons.
    GO:0045943    positive regulation of transcription from RNA polymerase I promoter    Any process that activates or increases the frequency, rate or extent of transcription from an RNA polymerase I promoter.
    GO:0045893    positive regulation of transcription, DNA-templated    Any process that activates or increases the frequency, rate or extent of cellular DNA-templated transcription.
    GO:0006355    regulation of transcription, DNA-templated    Any process that modulates the frequency, rate or extent of cellular DNA-templated transcription.
    GO:0006351    transcription, DNA-templated    The cellular synthesis of RNA on a template of DNA.
cellular component
    GO:0031965    nuclear membrane    Either of the lipid bilayers that surround the nucleus and form the nuclear envelope; excludes the intermembrane space.
    GO:0005730    nucleolus    A small, dense body one or more of which are present in the nucleus of eukaryotic cells. It is rich in RNA and protein, is not bounded by a limiting membrane, and is not seen during mitosis. Its prime function is the transcription of the nucleolar DNA into 45S ribosomal-precursor RNA, the processing of this RNA into 5.8S, 18S, and 28S components of ribosomal RNA, and the association of these components with 5S RNA and proteins synthesized outside the nucleolus. This association results in the formation of ribonucleoprotein precursors; these pass into the cytoplasm and mature into the 40S and 60S subunits of the ribosome.
    GO:0005654    nucleoplasm    That part of the nuclear content other than the chromosomes or the nucleolus.
    GO:0005634    nucleus    A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.
