PEPTIDES RECEPTORS Meaning and
Definition
-
Peptide receptors refer to specialized proteins located on the surface or within the cells of an organism that bind to specific peptides or small proteins known as peptides. These receptors are a crucial part of the cell signaling process, playing a vital role in transmitting messages and regulating various physiological functions.
Peptides, which are short chains of amino acids, act as signaling molecules that are involved in a wide range of biological processes. They can include hormones, neuropeptides, and neurotransmitters, among others. Peptide receptors are classically transmembrane proteins, spanning the cell membrane with an extracellular domain that binds to the specific peptide or protein and an intracellular domain that transmits the signal into the cell.
When a peptide binds to its complementary receptor, it triggers a cascade of events within the cell, initiating a signaling pathway that leads to various cellular responses. This can include the activation or inhibition of specific enzymes, the opening or closing of ion channels, changes in gene expression, or modulation of neurotransmitter release, among others.
Peptide receptors are diverse and varied, with different receptor subtypes recognizing specific peptide ligands. These receptors can be found in various tissues and organs throughout the body and are key regulators of multiple physiological processes, including growth and development, metabolism, reproduction, immune responses, and neurotransmission.
Research on peptide receptors and their ligands has contributed to the development of therapeutic drugs targeting these receptors for the treatment of various diseases, such as diabetes, obesity, cancer, and neurological disorders. Additionally, peptide receptors are important targets in drug discovery and pharmaceutical research for identifying potential new drug candidates.

Etymology of PEPTIDES RECEPTORS
The word "peptide" comes from the Greek word "peptos", which means "digested" or "well-cooked". The suffix "-ide" in "peptide" is used to denote a class of compounds. In chemistry, peptides refer to short chains of amino acids linked together by peptide bonds.
The word "receptor" originates from the Latin word "receptus", which means "to receive" or "to take in". In the context of biology, a receptor is a molecule typically found on the surface of cells that recognizes and binds to specific substances, such as hormones, neurotransmitters, or other signaling molecules.
When combined, "peptides receptors" refers to receptors that specifically bind to peptides. These can be receptors found on cell surfaces that are activated by peptide ligands or antibodies used to target and bind to specific peptides.
