Modulation of the activity of the enzyme ornithine decarboxylase.

The chemical reactions involving a pyrimidine deoxynucleotide, a compound consisting of nucleoside (a pyrimidine base linked to a deoxyribose sugar) esterified with a phosphate moiety at either the 3' or 5'-hydroxyl group of its glycose moiety.

Any series of molecular signals generated as a consequence of a glucocorticoid binding to its receptor.

The formation from simpler components of polyisoprenoids, acyclic polymers containing a large number of isoprene subunits, usually unsaturated.

Interacting selectively and stoichiometrically with neuropeptides, peptides with direct synaptic effects (peptide neurotransmitters) or indirect modulatory effects on the nervous system (peptide neuromodulators).

Catalysis of the reaction: myo-inositol 1-phosphate + H2O = myo-inositol + phosphate.

Catalysis of the reactions: reduced ferredoxin + NAD+ = oxidized ferredoxin + NADH + H+ and reduced ferredoxin + NADP+ = oxidized ferredoxin + NADPH + H+.

The formation from simpler components of glycolipid, a compound containing (usually) 1-4 linked monosaccharide residues joined by a glycosyl linkage to a lipid.

The directed movement of a purine nucleoside, a purine base covalently bonded to a ribose or deoxyribose sugar, into, out of, within or between cells.

Process by which a cell becomes capable of differentiating autonomously into a mesoderm cell regardless of its environment; upon determination, the cell fate cannot be reversed.

Catalysis of the reaction: an alpha-L-fucoside + H2O = an alcohol + L-fucose.

Process by which a cell becomes capable of differentiating autonomously into a mesoderm cell in an environment that is neutral with respect to the developmental pathway; upon specification, the cell fate can be reversed.

Catalysis of the hydrolysis of terminal non-reducing N-acetyl-D-glucosamine residues in N-acetyl-alpha-D-glucosaminides.

The process whose specific outcome is the progression of the fat body over time, from its formation to the mature structure. A fat body is an insect gland dorsal to the insect gut, with a function analogous to that of the vertebrate liver. It is a storage organ for fats, glycogen and protein and is a major site of intermediary metabolism.
