Any series of molecular signals generated as a consequence of an integrin binding to one of its physiological ligands.

Any of several heterotetrameric complexes that link clathrin (or another coat-forming molecule, as hypothesized for AP-3 and AP-4) to a membrane surface; they are found on coated pits and coated vesicles, and mediate sorting of cargo proteins into vesicles.

Catalysis of the reaction: ATP + FMN = diphosphate + FAD.

The covalent or noncovalent linking of a chromophore to a protein.

The series of molecular signals generated as a consequence of a serotonin receptor binding to one of its physiological ligands.

A vesicle that mediates transport between the trans-Golgi network and other parts of the cell.

Catalysis of the hydrolysis of alpha-L-iduronosidic linkages in desulfated dermatan.

The series of molecular signals generated as a consequence of an octopamine/tyramine receptor binding to one of its physiological ligands.

A small subcellular vesicle, surrounded by a single-layered membrane, that is formed from the Golgi apparatus and contains a highly concentrated protein destined for secretion. Secretory granules move towards the periphery of the cell, their membranes fuse with the cell membrane, and their protein load is exteriorized. Processing of the contained protein may take place in secretory granules.

Catalysis of the reaction: L-serine = pyruvate + NH3.

The series of molecular signals generated as a consequence of a dopamine receptor binding to one of its physiological ligands.

A vesicle that mediates transport from the Golgi to the endoplasmic reticulum.

Catalysis of the reaction: N-acetyl-L-glutamate 5-semialdehyde + NADP+ + phosphate = N-acetyl-5-glutamyl phosphate + NADPH + H+.

acetylcholine receptor signaling, muscarinic pathway

acetylcholine receptor signalling, muscarinic pathway

The series of molecular signals generated as a consequence of a muscarinic acetylcholine receptor binding to one of its physiological ligands; muscarinic acetylcholine receptors activate inhibitory G proteins and can be activated by the fungal alkaloid muscarine.
