That part of the nuclear content other than the chromosomes or the nucleolus.

A ribonuclease P complex located in the nucleolus of a eukaryotic cell, where it catalyzes the 5' endonucleolytic cleavage of precursor tRNAs to yield mature tRNAs. Eukaryotic nucleolar ribonuclease P complexes generally contain a single RNA molecule that is necessary but not sufficient for catalysis, and several protein molecules.

Interacting selectively with lactose, a disaccharide of glucose and galactose, the carbohydrate of milk.

The Y-shaped region of a replicating DNA molecule, resulting from the separation of the DNA strands and in which the synthesis of new strands takes place. Also includes associated protein complexes.

Interacting selectively and non-covalently with ubiqutin, a protein that when covalently bound to other cellular proteins marks them for proteolytic degradation.

regulation of Rac protein signal transduction

Any process that modulates the frequency, rate or extent of Rac protein signal transduction.

A complex of four polypeptides, comprising large and small DNA polymerase alpha subunits and two primase subunits, which catalyzes the synthesis of an RNA primer on the lagging strand of replicating DNA; the smaller of the two primase subunits alone can catalyze oligoribonucleotide synthesis.

Catalysis of the reaction: ATP + deoxyribonucleotide(n) + deoxyribonucleotide(m) = AMP + diphosphate + deoxyribonucleotide(n+m).

A change in state or activity of an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of exposure to acid.

A multimeric enzyme complex, which in humans is a heterotetramer of four subunits of approximately 125, 50, 68 and 12kDa. Also includes the delta DNA polymerase cofactor. Functions in DNA replication, mismatch repair and excision repair.

positive regulation of Rac protein signal transduction

Any process that activates or increases the frequency, rate or extent of Rac protein signal transduction.

Catalysis of the reaction: deoxynucleoside triphosphate + DNA(n) = diphosphate + DNA(n+1).
