regulatory peptide
Bioactive peptide molecules that modulate physiological processes through specific receptor interactions in neuroendocrine systems.
Full Definition
Regulatory peptides are a diverse family of bioactive molecules that serve as chemical messengers in neuroendocrine communication systems. These peptides range from small molecules with only a few amino acids to larger proteins, and they exert their effects by binding to specific membrane or intracellular receptors. Regulatory peptides can function as hormones, neurotransmitters, or neuromodulators depending on their site of action and mechanism of release. They play crucial roles in controlling various physiological processes including metabolism, growth, reproduction, stress response, and homeostasis. Many regulatory peptides are co-localized within the same neuroendocrine cells and can be co-released to provide coordinated physiological responses.
