Catalysis of the reaction: GTP + 2 H2O = formate + 2-amino-4-hydroxy-6-(erythro-1,2,3-trihydroxypropyl)-dihydropteridine triphosphate.

Small membrane-bounded organelle formed by pinching off of a coated region of membrane. Some coats are made of clathrin, whereas others are made from other proteins.

A vesicle with a coat formed of clathrin connected to the membrane via one of the clathrin adaptor complexes.

A vesicle with a coat formed of the COPI coat complex proteins. COPI-coated vesicles are found associated with Golgi membranes at steady state, are involved in Golgi to endoplasmic reticulum (retrograde) vesicle transport, and possibly also in intra-Golgi transport.

Catalysis of the reaction: IMP + H2O = 5-formamido-1-(5-phosphoribosyl)imidazole-4-carboxamide.

Catalysis of the reaction: inosine 5'-phosphate + NAD+ + H2O = xanthosine 5'-phosphate + NADH + H+.

A series of reactions initiated by the activation of the transcription factor NF-kappaB. NF-kappaB is sequestered by the inhibitor I-kappaB, and is released when I-kappaB is phosphorylated by activated I-kappaB kinase.

A membrane-bounded intracellular vesicle formed by invagination of the plasma membrane around an extracellular substance.

Catalysis of the reaction: L-iditol + NAD+ = L-sorbose + NADH + H+.

The series of molecular signals initiated in response to osmotic change.

osmosensory signaling pathway via Sho1 osmosensor

osmosensory signalling pathway via Sho1 osmosensor

A series of molecular signals generated in response to osmotic change, as mediated through a Sho1 osmosensor system.

osmosensory signaling pathway via two-component system

osmosensory signalling pathway via two-component system

A series of molecular signals generated in response to osmotic change, as mediated through a two-component (phosphorelay) system.

Any process that modulates the frequency, rate or extent of endocytosis.

The change in morphology and behavior of a natural killer cell in response to a cytokine, chemokine, cellular ligand, pathogen, or soluble factor.
