substance P receptor activity
Definition
Target type: molecularfunction
Combining with substance P, the peptide Arg-Pro-Lys-Pro-Gln-Gln-Phe-Phe-Gly-Leu-Met, to initiate a change in cell activity. [GOC:mah, ISBN:0198506732]
Substance P receptor activity is a molecular function associated with the G protein-coupled receptor (GPCR) known as the neurokinin-1 receptor (NK1R). This receptor is activated by the neuropeptide substance P, which plays a significant role in various physiological processes, including pain perception, inflammation, neurotransmission, and mood regulation. The binding of substance P to NK1R triggers a cascade of intracellular signaling events. The receptor undergoes conformational changes, leading to the activation of G proteins, primarily Gq, which in turn activates phospholipase C (PLC). PLC hydrolyzes phosphatidylinositol 4,5-bisphosphate (PIP2) into diacylglycerol (DAG) and inositol trisphosphate (IP3). DAG activates protein kinase C (PKC), while IP3 triggers the release of calcium from intracellular stores. These signaling pathways ultimately lead to a range of cellular responses, including changes in gene expression, neuronal excitability, and the release of other neurotransmitters. The molecular function of substance P receptor activity is essential for mediating the effects of substance P and plays a critical role in regulating various physiological functions. In the context of pain perception, for instance, substance P receptor activation contributes to the sensation of pain and the inflammatory response.'
