A process that identifies and degrades defective or aberrant RNAs within the nucleus.

The set of processes involved in identifying and degrading defective or aberrant ncRNAs within the nucleus.

Catalysis of the cleavage of the amide bond to release lipoic acid from a lipoylated protein.

The chemical reactions and pathways resulting in the breakdown of UMP, uridine monophosphate.

A catalytic protein complex that is capable of alpha-D-ribose 1-methylphosphonate 5-triphosphate synthase activity.

Catalysis of the reaction: ATP + methylphosphonate = alpha-D-ribose 1-methylphosphonate 5-triphosphate + adenine.

The chemical reactions and pathways resulting in the breakdown of UTP, uridine (5'-)triphosphate.

Any process that reduces or removes the toxicity of hydrogen peroxide in a cell. These include transport of hydrogen peroxide away from sensitive areas and to compartments or complexes whose purpose is sequestration.

The chemical reactions and pathways resulting in the breakdown of dGMP, deoxyguanosine monophosphate (2'-deoxyguanosine 5'-phosphate).

OBSOLETE. A positive regulation of transcription from RNA polymerase II promoter that results in positive regulation of filamentous growth of a population of unicellular organisms in response to starvation.

The aggregation, arrangement and bonding together of a set of components to form an Atg1/UKL1 kinase complex.

Any process that modulates the frequency, rate or extent of protein localization to nucleolus.

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.

A spliceosomal complex that is formed by association of the 5' splice site and the branch point sequence with specific snRNPs. The prespliceosome includes many proteins in addition to those found in the bound snRNPs. Commitment to a given pair of 5' and 3' splice sites occurs at the time of prespliceosome formation. Prespliceosome complexes are not active for splicing, but are instead an early step in the assembly of a spliceosomal complex.

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.

A spliceosomal complex that is formed by the displacement of the two snRNPs from the precatalytic spliceosome; three snRNPs including U5 remain associated with the mRNA. This complex, sometimes called the activated spliceosome, is the catalytically active form of the spliceosome, and includes many proteins in addition to those found in the associated snRNPs.

The chemical reactions and pathways resulting in the breakdown of TMP, ribosylthymine monophosphate.

A spliceosomal complex that is formed by the cooperative binding of the heterodimeric U11/U12 snRNP to the 5' splice site and the branch point sequence. The U12-type prespliceosome includes many proteins in addition to those found in the U11/U12 heterodimeric snRNPs. Commitment to a given pair of 5' and 3' splice sites occurs at the time of prespliceosome formation.
