Asymmetric/Biological Unit(hide GO term definitions)
Chain A   (SMYD3_HUMAN | Q9H7B4)
molecular function
    GO:0000993    RNA polymerase II core binding    Interacting selectively and non-covalently with RNA polymerase II core enzyme, a multisubunit eukaryotic nuclear RNA polymerase typically composed of twelve subunits.
    GO:0000979    RNA polymerase II core promoter sequence-specific DNA binding    Interacting selectively and non-covalently with the regulatory region composed of the transcription start site and binding sites for transcription factors of the RNA polymerase II basal transcription machinery.
    GO:0001162    RNA polymerase II intronic transcription regulatory region sequence-specific DNA binding    Interacting selectively and non-covalently with an RNA polymerase II intronic DNA sequence that regulates the transcription of the transcript it is contained within.
    GO:0018024    histone-lysine N-methyltransferase activity    Catalysis of the reaction: S-adenosyl-L-methionine + histone L-lysine = S-adenosyl-L-homocysteine + histone N6-methyl-L-lysine. The methylation of peptidyl-lysine in histones forms N6-methyl-L-lysine, N6,N6-dimethyl-L-lysine and N6,N6,N6-trimethyl-L-lysine derivatives.
    GO:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
    GO:0008168    methyltransferase activity    Catalysis of the transfer of a methyl group to an acceptor molecule.
    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.
biological process
    GO:0071549    cellular response to dexamethasone stimulus    Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a dexamethasone stimulus.
    GO:0045184    establishment of protein localization    The directed movement of a protein to a specific location.
    GO:0034968    histone lysine methylation    The modification of a histone by addition of one or more methyl groups to a lysine residue.
    GO:0032259    methylation    The process in which a methyl group is covalently attached to a molecule.
    GO:0014904    myotube cell development    The process aimed at the progression of a myotube cell over time, from initial commitment of the cell to a specific fate, to the fully functional differentiated cell. Myotubes are multinucleated cells that are formed when proliferating myoblasts exit the cell cycle, differentiate and fuse.
    GO:0006469    negative regulation of protein kinase activity    Any process that stops, prevents, or reduces the frequency, rate or extent of protein kinase activity.
    GO:0006334    nucleosome assembly    The aggregation, arrangement and bonding together of a nucleosome, the beadlike structural units of eukaryotic chromatin composed of histones and DNA.
    GO:0033138    positive regulation of peptidyl-serine phosphorylation    Any process that activates or increases the frequency, rate or extent of the phosphorylation of peptidyl-serine.
    GO:0045944    positive regulation of transcription from RNA polymerase II promoter    Any process that activates or increases the frequency, rate or extent of transcription from an RNA polymerase II promoter.
cellular component
    GO:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
    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.
