Orexin B

Product Details – Orexin B

Orexin B is a neuropeptide derived from the precursor molecule prepro-orexin, which is processed into orexin A and orexin B through enzymatic cleavage. It is naturally associated with hypothalamic signaling systems and is studied for its role in neuropeptide-receptor interactions.

In controlled laboratory environments, orexin B is utilized to investigate receptor binding behavior and intracellular signaling pathways associated with neuropeptide activity. Its defined amino acid structure allows for consistent evaluation of peptide-receptor dynamics and signal transduction mechanisms.

This compound is supplied strictly for laboratory research purposes and is not intended for consumption, medical, or diagnostic use.

Mechanism of Action

At the molecular level, orexin B is studied for its interaction with orexin receptors, particularly orexin receptor 2 (OX2R), which belongs to the G protein-coupled receptor (GPCR) family. Upon binding, the receptor-ligand complex initiates intracellular signaling cascades, including calcium ion mobilization and downstream second messenger activity.

These signaling events are analyzed in vitro to evaluate receptor activation, ligand affinity, and intracellular communication pathways. Researchers examine how orexin B influences neurotransmitter-related signaling systems through receptor-mediated mechanisms.

Additionally, orexin B is investigated for its role in modulating neuropeptide signaling networks, contributing to a broader understanding of receptor-specific activation and molecular pathway regulation under controlled experimental conditions.
