Apelin Receptor Signaling During Mesoderm Development.

The Apelin receptor (Aplnr) is a G-protein coupled receptor which has a wide body distribution and various physiological roles including homeostasis, angiogenesis, cardiovascular and neuroendocrine function. Apelin and Elabela are two peptide components of the Aplnr signaling and are cleaved to give different isoforms which are active in different tissues and organisms.
