About: Proctolin

An Entity of Type: protein, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

Proctolin is a neuropeptide present in insects and crustaceans. It was first found in Periplaneta americana, a species of cockroach in 1975. Proctolin was extracted from 125,000 cockroaches and the Edman degradation was carried out on the sample to determine the amino acid sequence, which is Arg-Tyr-Leu-Pro-Thr. Proctolin was the first insect neuropeptide to be sequenced. Starratt and Brown identified it as a visceral muscle neurotransmitter. However, it now appears that there are many more functions of proctolin, and it is present in many more species.

dbo:abstract
  • Das Proctolin (englisch synonym) bezeichnet eine aus fünf Aminosäuren bestehendes Neuropeptid (H-Arg-Tyr-Leu-Pro-Thr-OH), das bei Insekten für die neuromuskulären Synapsen der im Bereich des Enddarms als Neurotransmitter fungiert. Darüber hinaus ist Proctolin immunologisch auch im Zentralnervensystem von Insekten und sogar von Wirbeltieren als weit verbreitet nachzuweisen. Ihm wird eine generelle Neurotransmitterfunktion zugeschrieben. (de)
