1.MECHANISM OF ACTION

Neuropeptide K, porcine is a 36-amino acid, C-terminally amidated member of the tachykinin peptide family, exerting diverse physiological effects via binding to tachykinin receptors (NK1 and NK2). As a multi-functional neuropeptide, it activates G-protein coupled receptor (GPCR)-mediated intracellular signaling pathways upon receptor ligation: binding to NK1/NK2 receptors triggers hydrolysis of phosphatidylinositol 4,5-bisphosphate (PIP2), generating inositol trisphosphate (IP3) and diacylglycerol (DAG), which elevate intracellular calcium levels to mediate downstream responses.

2.PRODUCT INDICATIONS

Investigation of tachykinin receptor (NK1/NK2) signaling pathways and their roles in vasodilation, neurotransmission, and hormone secretion

Screening and validation of tachykinin receptor agonists/antagonists via in vitro assays (receptor binding, calcium mobilization, and smooth muscle relaxation assays)

Study of species-specific tachykinin family biology using porcine models to elucidate Neuropeptide K-mediated physiological processes

3.CLINICAL EFFICACY OF PRODUCT

In vascular smooth muscle assays, it serves as a reliable positive control to evaluate the efficacy of tachykinin-targeted drugs for cardiovascular disorders (e.g., hypertension, vasospasm)

In porcine and rodent models of metabolic disorders, it aids in elucidating the role of Neuropeptide K in appetite suppression, supporting the development of novel therapeutics for obesity and eating disorders

It facilitates the characterization of tachykinin signaling in neuronal excitation and neurotransmitter release, providing insights for developing treatments for neurological disorders linked to dysregulated tachykinin pathways
