"Apelin peptides are the cognate ligands for the G-protein coupled receptor APJ, with functions in the cardiovascular and central nervous systems, in glucose metabolism and as a human immunodeficiency virus (HIV-1) coreceptor. Apelin is found in 13-36 residue forms in vivo," scientists in Halifax, Canada report.

"The structures of five isoforms of apelin at physiological versus low (5-6 degrees C) temperature are compared here using circular dichroism (CD) and nuclear magnetic resonance (NMR) spectroscopy, demonstrating increased structure at low temperature. Far-ultraviolet (UV) CD spectra are predominantly random coil for apelin isoforms, but are convoluted by unusual...
