molecular function
    GO:0016407    acetyltransferase activity    Catalysis of the transfer of an acetyl group to an acceptor molecule.
    GO:0019899    enzyme binding    Interacting selectively and non-covalently with any enzyme.
    GO:0004402    histone acetyltransferase activity    Catalysis of the reaction: acetyl-CoA + histone = CoA + acetyl-histone.
    GO:0046972    histone acetyltransferase activity (H4-K16 specific)    Catalysis of the reaction: acetyl-CoA + histone H4 L-lysine (position 16) = CoA + histone H4 N6-acetyl-L-lysine (position 16). This reaction represents the addition of an acetyl group to the lysine at position 16 of histone H4.
    GO:0043995    histone acetyltransferase activity (H4-K5 specific)    Catalysis of the reaction: acetyl-CoA + histone H4 L-lysine (position 5) = CoA + histone H4 N6-acetyl-L-lysine (position 5).
    GO:0043996    histone acetyltransferase activity (H4-K8 specific)    Catalysis of the reaction: acetyl-CoA + histone H4 L-lysine (position 8) = CoA + histone H4 N6-acetyl-L-lysine (position 8).
    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: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:0008134    transcription factor binding    Interacting selectively and non-covalently with a transcription factor, any protein required to initiate or regulate transcription.
    GO:0016740    transferase activity    Catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor). Transferase is the systematic name for any enzyme of EC class 2.
    GO:0016746    transferase activity, transferring acyl groups    Catalysis of the transfer of an acyl group from one compound (donor) to another (acceptor).
    GO:0016747    transferase activity, transferring acyl groups other than amino-acyl groups    Catalysis of the transfer of an acyl group, other than amino-acyl, from one compound (donor) to another (acceptor).
biological process
    GO:0043984    histone H4-K16 acetylation    The modification of histone H4 by the addition of an acetyl group to a lysine residue at position 16 of the histone.
    GO:0043981    histone H4-K5 acetylation    The modification of histone H4 by the addition of an acetyl group to a lysine residue at position 5 of the histone.
    GO:0043982    histone H4-K8 acetylation    The modification of histone H4 by the addition of an acetyl group to a lysine residue at position 8 of the histone.
    GO:0016573    histone acetylation    The modification of a histone by the addition of an acetyl group.
    GO:0030099    myeloid cell differentiation    The process in which a relatively unspecialized myeloid precursor cell acquires the specialized features of any cell of the myeloid leukocyte, megakaryocyte, thrombocyte, or erythrocyte lineages.
    GO:0045892    negative regulation of transcription, DNA-templated    Any process that stops, prevents, or reduces the frequency, rate or extent of cellular DNA-templated transcription.
    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:0010506    regulation of autophagy    Any process that modulates the frequency, rate or extent of autophagy. Autophagy is the process in which cells digest parts of their own cytoplasm.
    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:0071339    MLL1 complex    A protein complex that can methylate lysine-4 of histone H3. MLL1/MLL is the catalytic methyltransferase subunit, and the complex also contains the core components ASH2L, HCFC1/HCF1 WDR5 and RBBP5.
    GO:0072487    MSL complex    A histone acetyltransferase complex that catalyzes the acetylation of a histone H4 lysine residue at position 16. In human, it contains the catalytic subunit MOF, and MSL1, MSL2 and MSL3.

    GO:0000123    histone acetyltransferase complex    A protein complex that possesses histone acetyltransferase activity.
    GO:0000776    kinetochore    A multisubunit complex that is located at the centromeric region of DNA and provides an attachment point for the spindle microtubules.
    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.

Chain B   (MSL1_MOUSE | Q6PDM1)
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.
