Transferase is the systematic name for any enzyme of EC class 2."

[GOC:mah] EOG8ZPH8Z GO:0000398 1/92 mRNA splicing, via spliceosome biological_process "The joining together of exons from one or more primary transcripts of messenger RNA (mRNA) and the excision of intron sequences, via a spliceosomal mechanism, so that mRNA consisting only of the joined exons is produced." [GOC:krc, ISBN:0198506732, ISBN:0879695897] EOG8ZPH8Z GO:0071013 1/92 catalytic step 2 spliceosome cellular_component "A spliceosomal complex that contains three snRNPs, including U5, bound to a splicing intermediate in which the first catalytic cleavage of the 5' splice site has occurred. The precise subunit composition differs significantly from that of the catalytic step 1, or activated, spliceosome, and includes many proteins in addition to those found in the associated snRNPs."

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." [GOC:go_curators] EOG8ZPH8Z GO:0045893 1/92 positive regulation of transcription, DNA-templated biological_process "Any process that activates or increases the frequency, rate or extent of cellular DNA-templated transcription." [GOC:go_curators, GOC:txnOH] EOG8ZPH8Z GO:0006351 1/92 transcription, DNA-templated biological_process "The cellular synthesis of RNA on a template of DNA." [GOC:jl, GOC:txnOH] EOG8ZPH8Z GO:0003677 1/92 DNA binding molecular_function "Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid)." [GOC:dph, GOC:jl, GOC:tb, GOC:vw] EOG8ZPH8Z GO:0005730 1/92 nucleolus cellular_component "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." [ISBN:0198506732] EOG8ZPH8Z GO:0071011 1/92 precatalytic spliceosome cellular_component "A spliceosomal complex that is formed by the recruitment of a preassembled U5-containing tri-snRNP to the prespliceosome. Although all 5 snRNPs are present, the precatalytic spliceosome is catalytically inactive. The precatalytic spliceosome includes many proteins in addition to those found in the associated snRNPs."
