描述
Imidazoleacetic acid ribotide (IAA-RP ) is an endogenous ligand that stimulates imidazol(in)e receptors. Experimental data suggest that IAA-RP may participate in transsynaptic signaling in brain, because it exists in brainstem neurons, exhibits depolarization-induced Ca2+-dependent release from P2 synaptosomal elements, has relatively high affinity for membrane-bound I-R sites, and produces physiological effects on exogenous application. IAA-RP is rapidly metabolized by phosphatases and ecto-5'-nucleotidases. (PMID: 15365189) [HMDB]
