The chemical reactions involving estrogens, C18 steroid hormones that can stimulate the development of female sexual characteristics. Also found in plants.

The chemical reactions involving glucocorticoids, hormonal C21 corticosteroids synthesized from cholesterol. Glucocorticoids act primarily on carbohydrate and protein metabolism, and have anti-inflammatory effects.

The addition of an alkyl group to a protein amino acid. An alkyl group is any group derived from an alkane by removal of one hydrogen atom.

Combining with anaphylatoxin to initiate a change in cell activity.

The removal of an alkyl group from a protein amino acid. An alkyl group is any group derived from an alkane by removal of one hydrogen atom.

Combining with anaphylatoxin C3a to initiate a change in cell activity.

The chemical reactions involving spermine, a polybasic amine found in human sperm, in ribosomes and in some viruses, which is involved in nucleic acid packaging. Synthesis is regulated by ornithine decarboxylase which plays a key role in control of DNA replication.

Combining with anaphylatoxin C5a to initiate a change in cell activity.

The chemical reactions involving spermidine, N-(3-aminopropyl)-1,4-diaminobutane.

The process that modulates the force with which blood travels through the circulatory system.

Combining with bombesin to initiate a change in cell activity.

Combining with bradykinin to initiate a change in cell activity.

The specific activation or halting of processes within a cell so that its vital functions markedly cease, rather than simply deteriorating gradually over time, which culminates in cell death.

Combining with calcitonin to initiate a change in cell activity.

Combining with cannabinoids to initiate a change in cell activity.

Catalysis of the release of C-terminal dipeptides from a polypeptide chain.

A receptor that binds an extracellular ligand and transmits the signal to a heterotrimeric G-protein complex. These receptors are characteristically seven-transmembrane receptors and are made up of hetero- or homodimers.
