A comparative study of neurotensin inactivation by brain peptidases from different vertebrate species. 1984

E C Griffiths, and J R McDermott, and A I Smith

The products formed from mammalian neurotensin by peptidases in two subcellular fractions from rat, mouse, dove, terrapin and goldfish brain were separated and identified using high-performance liquid chromatography. The main neurotensin metabolites were [1-8]-, [1-10]- and [1-7]-sequences; goldfish and terrapin brain fractions also produced [1-11]- and [1-12]-fragments. Avian neurotensin was cleaved by peptidases in rat and dove brain fractions to [1-8]-, [9-13]-, [1-10]- and [1-12]-fragments. Similar mechanisms of inactivation were found for both mammalian and avian neurotensins .

UI MeSH Term Description Entries
D008297 Male Males
D009496 Neurotensin A biologically active tridecapeptide isolated from the hypothalamus. It has been shown to induce hypotension in the rat, to stimulate contraction of guinea pig ileum and rat uterus, and to cause relaxation of rat duodenum. There is also evidence that it acts as both a peripheral and a central nervous system neurotransmitter.
D010450 Endopeptidases A subclass of PEPTIDE HYDROLASES that catalyze the internal cleavage of PEPTIDES or PROTEINS. Endopeptidase,Peptide Peptidohydrolases
D011894 Rana pipiens A highly variable species of the family Ranidae in Canada, the United States and Central America. It is the most widely used Anuran in biomedical research. Frog, Leopard,Leopard Frog,Lithobates pipiens,Frogs, Leopard,Leopard Frogs
D011919 Rats, Inbred Strains Genetically identical individuals developed from brother and sister matings which have been carried out for twenty or more generations or by parent x offspring matings carried out with certain restrictions. This also includes animals with a long history of closed colony breeding.

D001921 Brain The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM. Encephalon
D005260 Female Females
D006054 Goldfish Common name for Carassius auratus, a type of carp (CARPS). Carassius auratus
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA. Animal,Metazoa,Animalia
D001717 Birds Warm-blooded VERTEBRATES possessing FEATHERS and belonging to the class Aves. Aves,Bird
