Substance P receptors in mammalian central nervous system.
1. Multiple distinct affinity states or sites of substance P (SP) receptors exist in freshly-prepared rat brain membranes. 2. Substance P receptors may couple with islet-activating protein (pertussis toxin) sensitive GTP-binding protein(s). 3. Substance P receptors may be regulated Mg2+ and Na+ in an opposite manner. 4. Some important factor(s), in addition to GTP-binding protein, appear to be involved in SP binding activity. 5. An apparent molecular weight of the SP binding site is approximately 46,000 Da.
