Description
Curator's Comment: description was created based on several sources, including https://www.drugbank.ca/drugs/DB00129

Ornithine is an amino acid produced in the urea cycle by the splitting off of urea from arginine. It is a central part of the urea cycle, which allows for the disposal of excess nitrogen. Ornithine is also a precursor of citrulline and arginine. Arginine stimulates the pituitary release of growth hormone. Burns or other injuries affect the state of arginine in tissues throughout the body. As de novo synthesis of arginine during these conditions is usually not sufficient for normal immune function, nor for normal protein synthesis, ornithine may have immunomodulatory and wound-healing activities under these conditions (by virtue of its metabolism to arginine).

CNS Activity

Curator's Comment: Known to be CNS active in mouse. Human data not available.

Measurement of Ca2+-dependent chloride currents in Xenopus laevis oocytes facilitated the deorphanization of human family C G-protein-coupled receptor hGPRC6A/homologous goldfish 5.24 receptor chimeric construct (h6A/5.24) and identification of L-amino acids as agonists. The most active agonists were L-Arg, L-Lys, and L-ornithine, suggesting that these may function as endogenous signaling molecules (only L-Arg, L-Lys, and L-ornithine were able to activate h6A/5.24 at 10 uM concentration).
