| + | [https://www.uniprot.org/uniprot/3SI1A_DENAN 3SI1A_DENAN] Orthosteric antagonist of the alpha-1A adrenergic receptor (ADRA1A) with an affinity of 0.35 nM (PubMed:20015090). Has also affinity for ADRA1B > ADRA2C > ADRA1D (PubMed:23935897). Acts as a relaxant of smooth muscle. Reduces prostatic muscle tone as efficiently as tamsulosin (an antagonist presently used), but with fewer cardiovascular side effects (PubMed:23005263).<ref>PMID:20015090</ref> <ref>PMID:21419153</ref> <ref>PMID:23005263</ref> <ref>PMID:23935897</ref> | ||

| + | rho-Da1a toxin from eastern green mamba (Dendroaspis angusticeps) venom is a polypeptide of 65 amino acids with a strong affinity for the G-protein-coupled alpha(1A)-adrenoceptor. This neurotoxin has been crystallized from resolubilized lyophilized powder, but the best crystals grew spontaneously during lyophilization. The crystals belonged to the trigonal space group P3(1)21, with unit-cell parameters a = b = 37.37, c = 66.05 A, and diffracted to 1.95 A resolution. The structure solved by molecular replacement showed strong similarities to green mamba muscarinic toxins. | ||
