apelin receptor early endogenous ligand

This gene encodes a peptide hormone that binds to the Apelin receptor. The encoded protein is required for heart development in zebrafish and has been shown to maintain self-renewal of human embryonic stem cells through activation of the PI3K/AKT pathway. Experiments in human and mouse cell lines point to additional roles for the encoded protein in angiogenesis and regulation of vascular tone. [provided by RefSeq, Jul 2016]

apelin receptor

This gene encodes a member of the G protein-coupled receptor gene family. The encoded protein is related to the angiotensin receptor, but is actually an apelin receptor that inhibits adenylate cyclase activity and plays a counter-regulatory role against the pressure action of angiotensin II by exerting hypertensive effect. It functions in the cardiovascular and central nervous systems, in glucose metabolism, in embryonic and tumor angiogenesis and as a human immunodeficiency virus (HIV-1) coreceptor. Two transcript variants resulting from alternative splicing have been identified. [provided by RefSeq, Jul 2009]

apelin

This gene encodes a peptide that functions as an endogenous ligand for the G-protein coupled apelin receptor. The encoded preproprotein is proteolytically processed into biologically active C-terminal peptide fragments. These peptide fragments activate different tissue specific signaling pathways that regulate diverse biological functions including fluid homeostasis, cardiovascular function and insulin secretion. This protein also functions as a coreceptor for the human immunodeficiency virus 1. [provided by RefSeq, Feb 2016]
