af-2 neuropeptide

Neuropeptide AF (human) acetate (Neuropeptide AF (human) acetate (192387-38-5 Free base)) is an anti-opioid neuropeptide, a Neuropeptide AF (human) derivative, which regulates adipocyte metabolism.

AF2 is the nematode neuropeptide. It also increases voltage-activated calcium currents in Ascaris suum muscle.

Neuropeptide AF (cattle), an amidated octadecapeptide and RFamide neuropeptide, serves as a ligand for Mas-related gene receptor A4 (MrgprA4) (Mas-related G-protein-coupled Receptor (MRGPR)) with an EC50 of approximately 60 nM, and MrgprC11 with an EC50 of around 300 nM. It activates G protein-coupled receptors NPFF1 (Neuropeptide Y Receptor) with an EC50 ranging from ~25 to 325 nM, and NPFF2 with an EC50 of approximately 1 to 5 nM. Additionally, Neuropeptide AF (cattle) exhibits anti-opiate effects and modulates related pain [1] [2].

Neuropeptide Y (2-36) (porcine) is a pig-sourced peptide closely resembling its rat and human counterparts with 97.14% homology. It acts as an agonist for rat neuropeptide receptors Y5, Y2, and Y1, with EC50 values of 1.2, 1.6, and 3.4 nM, respectively. This compound is utilized in research on obesity and eating disorders [1].

Neuropeptide AF (93-110), Human is an endogenous antiopioid peptide.
