Immuno-Grade Apelin Receptor Antibodies
The apelin receptor (APLNR) responds to apelin, a 36 amino-acid peptide which is cleaved from a 77 amino-acid precursor peptide. Apelin-36, apelin-13 and [Pyr1]apelin-13 are the predominant endogenous ligands. A second family of peptides named Elabela/Toddler has discovered independently as endogenous ligands. The apelin receptor is coupled to inhibitory G-proteins. A number of physiological roles for the receptor have emerged, including regulation of cardiovascular function, fluid homeostasis, the adipoinsular axis, gastrointestinal and immunomodulatory functions.
