Asymmetric/Biological Unit(hide GO term definitions)
Chain A,B   (CET1_YEAST | O13297)
molecular function
    GO:0016787    hydrolase activity    Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. Hydrolase is the systematic name for any enzyme of EC class 3.
    GO:0004651    polynucleotide 5'-phosphatase activity    Catalysis of the reaction: 5'-phosphopolynucleotide + H2O = polynucleotide + phosphate.
    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).
biological process
    GO:0006370    7-methylguanosine mRNA capping    Addition of the 7-methylguanosine cap to the 5' end of a nascent messenger RNA transcript.
    GO:0006397    mRNA processing    Any process involved in the conversion of a primary mRNA transcript into one or more mature mRNA(s) prior to translation into polypeptide.
    GO:0098507    polynucleotide 5' dephosphorylation    The process of removing one or more phosphate groups from the 5' end of a polynucleotide.
    GO:0098501    polynucleotide dephosphorylation    The process of removing one or more phosphate groups from a polynucleotide.
    GO:1900182    positive regulation of protein localization to nucleus    Any process that activates or increases the frequency, rate or extent of protein localization to nucleus.
    GO:0032968    positive regulation of transcription elongation from RNA polymerase II promoter    Any process that activates or increases the frequency, rate or extent of transcription elongation, the extension of an RNA molecule after transcription initiation and promoter clearance by the addition of ribonucleotides, catalyzed by RNA polymerase II.
cellular component
    GO:0031533    mRNA cap methyltransferase complex    A protein complex that consists of an RNA 5' triphosphatase and a guanyl transferase (Cet1p and Ceg1p in S. cerevisiae; Pct1 and Ceg1 in S. pombe) and is involved in mRNA capping.
    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 C,D   (MCE1_YEAST | Q01159)
molecular function
    GO:0005525    GTP binding    Interacting selectively and non-covalently with GTP, guanosine triphosphate.
    GO:0004484    mRNA guanylyltransferase activity    Catalysis of the reaction: GTP + (5')pp-Pur-mRNA = diphosphate + G(5')ppp-Pur-mRNA; G(5')ppp-Pur-mRNA is mRNA containing a guanosine residue linked 5' through three phosphates to the 5' position of the terminal residue.
    GO:0000166    nucleotide binding    Interacting selectively and non-covalently with a nucleotide, any compound consisting of a nucleoside that is esterified with (ortho)phosphate or an oligophosphate at any hydroxyl group on the ribose or deoxyribose.
    GO:0016779    nucleotidyltransferase activity    Catalysis of the transfer of a nucleotidyl group to a reactant.
    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: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:0006370    7-methylguanosine mRNA capping    Addition of the 7-methylguanosine cap to the 5' end of a nascent messenger RNA transcript.
    GO:0006397    mRNA processing    Any process involved in the conversion of a primary mRNA transcript into one or more mature mRNA(s) prior to translation into polypeptide.
    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.
