Description

General description

Substance P receptor (SPR), also known as neurokinin receptor 1 (NK-1 R), is a member of the G-protein-coupled class of seven transmembrane domain receptors. SPR gene with five exons, spanning 45-60kb on genomic DNA, is mapped to human chromosome 2. SPR is highly expressed in central nervous system.

Immunogen

synthetic peptide corresponding to the C-terminal of NK1R of rat origin (amino acids 393-407). This sequence is highly conserved in mouse, guinea pig, and human NK1R, but diverges in other tachykinin receptor subtypes NK2R and NK3R.

Application

Anti-substance P receptor antibody produced in rabbit has been used in immunohistochemistry.[1]

Biochem/physiol Actions

Substance P (SP) exhibits pro-inflammatory, endocrine, neuromodulatory and trophic activities. Substance P receptor (SPR) upon binding to its ligand SP, facilitates extravasation of granulocytes and in inflammation and tissue derangement. In addition, activation of this receptor also enhances metabolism of phosphoinositol, leading to synthesis of inositol-1,4,5-trisphosphate and diacylglycerol which results in release of Ca²⁺ from the endoplasmic reticulum and activation of protein kinase C. SPR along with its ligand stimulates tumoral angiogenesis and cell proliferation in a variety of cancer types. Inhibition of substance P receptor retards the growth of neuroblastoma (NB) cell lines. Thus, SPR might act as a potential therapeutic target for a large variety of patients with neuroblastoma. SP-SPR complex is also implicated in the regulation of the pain transmission.
