Product Overview

Oxytocin is a naturally occurring nonapeptide hormone and neuropeptide synthesized primarily in the hypothalamus and released from the posterior pituitary.

The peptide consists of nine amino acids and contains a characteristic disulfide bridge between two cysteine residues, creating a cyclic structure that is important to its molecular conformation.

Oxytocin has been extensively investigated in laboratory research involving neuropeptide signaling, receptor biology, smooth-muscle physiology, social and behavioral neuroscience, and endocrine signaling.

Its primary receptor, the oxytocin receptor (OXTR), is a G-protein-coupled receptor that mediates cellular responses to the peptide.

Mechanism of Action

Research has investigated oxytocin in relation to several biological mechanisms:

Oxytocin Receptor Signaling

Oxytocin interacts with the oxytocin receptor (OXTR), a G-protein-coupled receptor involved in intracellular calcium and signaling pathways.

Neuroendocrine Research

Oxytocin has been studied extensively as a neuroendocrine signaling molecule involved in communication between the hypothalamus, pituitary system, and peripheral tissues.

Smooth-Muscle Research

Experimental studies have investigated oxytocin receptor signaling in smooth-muscle tissues and associated cellular responses.

Social & Behavioral Research

Oxytocin is widely studied in neuroscience research examining social behavior, affiliative signaling, stress responses, and social cognition.

Cellular Signaling Research

Oxytocin provides a useful experimental model for studying peptide-receptor interactions and downstream intracellular signaling mechanisms.
