Anti-Apelin

Protein function: Endogenous ligand for the apelin receptor (APLNR) (PubMed:10525157). Drives internalization of the apelin receptor. Apelin-36 dissociates more hardly than (pyroglu)apelin-13 from APLNR. Hormone involved in the regulation of cardiac precursor cell movements during gastrulation and heart morphogenesis. Has an inhibitory effect on cytokine production in response to T-cell receptor/CD3 cross-linking, the oral intake of apelin in the colostrum and the milk might therefore modulate immune responses in neonates. Plays a role in early coronary blood vessels formation. Mediates myocardial contractility in an ERK1/2-dependent manner. May also have a role in the central control of body fluid homeostasis by influencing vasopressin release and drinking behavior. [The UniProt Consortium]
