Description
Oxytocin is a cyclic nonapeptide studied in controlled laboratory environments for its binding activity at oxytocin receptors (OXTRs) expressed across a range of tissue types, with research applications spanning neuroendocrine signaling, social behavior pathway modeling, and peripheral receptor pharmacology.
Key Characteristics
- Cyclic nine-amino-acid peptide with a characteristic disulfide bridge contributing to structural rigidity
- High-affinity ligand for the oxytocin receptor (OXTR), a Gq-coupled GPCR
- Studied across the central nervous system and peripheral tissue receptor models
- Relevant to research areas including neuroendocrine regulation, social behavior circuits, and uterine contractility signaling pathways
- Well-characterized compound with an extensive body of peer-reviewed preclinical data
Handling and Storage
Oxytocin’s disulfide structure requires careful storage to prevent oxidative degradation over time. Controlled temperature, low humidity, and limited light exposure are recommended throughout the research period. Maintaining proper conditions from receipt through use helps ensure sample integrity and consistent experimental results.
FAQs
What is Oxytocin?
Oxytocin is a cyclic nonapeptide studied in laboratory settings for its binding to oxytocin receptors (OXTRs) and the signaling pathways these interactions activate, spanning neuroendocrine, behavioral, and peripheral tissue research models.
What receptor does Oxytocin act on?
Oxytocin binds primarily to the OXTR, a Gq-coupled G protein-coupled receptor expressed in various central and peripheral tissues. This receptor interaction is the basis for most laboratory research involving the compound.
What tissue types express the oxytocin receptor in research models?
OXTR expression has been observed across a range of tissue types in preclinical models, including hypothalamic and limbic brain regions, uterine smooth muscle, mammary tissue, and cardiac cells — making Oxytocin a relevant compound across several distinct research contexts.
