Prevention of degradation of mRNA molecules. In the absence of compensating changes in other processes, the slowing of mRNA degradation can result in an overall increase in the population of active mRNA molecules.

Cascade of at least three protein kinase activities culminating in the phosphorylation and activation of a MAP kinase. MAPKKK cascades lie downstream of numerous signaling pathways.

Interacting selectively with a nucleotide, any compound consisting of a nucleoside that is esterified with (ortho)phosphate or an oligophosphate at any hydroxyl group on the glycose moiety.

The formation from simpler components of UTP, uridine (5'-)triphosphate.

regulation of receptor mediated endocytosis

Any process that modulates the frequency, rate or extent of receptor mediated endocytosis, the uptake of external materials by cells, utilizing receptors to ensure specificity of transport.

Catalysis of the identification and base-pairing of homologous sequences between single-stranded DNA and double-stranded DNA.

A protein complex that includes a ubiquitin-protein ligase (E3) and other proteins that may confer substrate specificity on the complex.

Interacting selectively with an interferon, a protein produced by the immune systems of many animals in response to a challenge by a foreign agent.

A ubiquitin ligase complex found in the nucleus.

The breakdown into simpler components of uracil, 2,4-dioxopyrimidine, one of the pyrimidine bases occurring in RNA, but not in DNA.

A ubiquitin ligase complex found in the cytoplasm.

The chemical reactions involving any pyrimidine nucleoside, one of a family of organic molecules consisting of a pyrimidine base covalently bonded to a sugar ribose (a ribonucleoside) or deoxyribose (a deoxyribonucleoside).

The creation of a single organelle from two or more organelles.

The enzymatic modification of the chemical structure of specific sites in rRNA.

The breakdown into simpler components of thymidine, deoxyribosylthymine thymine 2-deoxyriboside, a deoxynucleoside very widely distributed but occurring almost entirely as phosphoric esters in deoxynucleotides and deoxyribonucleic acid, DNA.
