The formation from simpler components of leukotriene, a pharmacologically active substance derived from a polyunsaturated fatty acid, such as arachidonic acid.

Movement of organelles, other microtubules and other particles along microtubules, mediated by motor proteins.

A membrane coat found on a coated vesicle.

The process of removing one or more phosphoric groups from a phosphorylated lipid, any member of a group of substances soluble in lipid solvents but only sparingly soluble in aqueous solvents.

Development of a photoreceptor, a cell that responds to incident electromagnetic radiation, particularly visible light.

The removal of tubulin heterodimers from one or both ends of a microtubule.

An adaptor complex that links clathrin to the membrane surface of a vesicle; vesicles with AP-1-containing coats are normally found primarily in the trans-Golgi network.

Any process that modulates the frequency, rate or extent of the formation from simpler components of interleukin-4.

Development of a photoreceptor, a sensory cell in the eye that reacts to the presence of light. They usually contain a pigment that undergoes a chemical change when light is absorbed, thus stimulating a nerve.

Catalysis of the reaction: peptidyl-L-lysine(or L-arginine) + H2O = peptide + L-lysine(or L-arginine). Function is activated by Co2+; inhibited by guanidinoethylmercaptosuccinic acid.

An adaptor complex that links clathrin to the membrane surface of a vesicle; vesicles with AP-2-containing coats are normally found primarily near the plasma membrane, on endocytic vesicles.

Catalysis of the reaction: L-ornithine = L-proline + NH3.

positive regulation of interleukin-4 biosynthesis

positive regulation of IL-4 biosynthesis

Any process that activates or increases the rate of the formation from simpler components of interleukin-4.

Catalysis of the reaction: palmitoyl-protein + H2O = palmitate + protein.

The chemical reactions involving galactolipids, any glycolipid containing one of more residues of galactose and/or N-acetylgalactosamine.
