Previous GeneCards Identifiers for APLN Gene
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]

UniProtKB/Swiss-Prot for APLN Gene
Endogenous ligand for APJ, an alternative coreceptor with CD4 for HIV-1 infection. Inhibits HIV-1 entry in cells coexpressing CD4 and APJ. Apelin-36 has a greater inhibitory activity on HIV infection than other synthetic apelin derivatives. The oral intake in the colostrum and the milk could have a role in the modulation of the immune responses in neonates. May also have a role in the central control of body fluid homeostasis by influencing AVP release and drinking behavior.
Apelin-36, apelin-13 and [Pyr1]-apelin-13 are the predominant endogenous ligands for the apelin receptor (APJ) receptor. The APJ receptor and apelin peptides act as mediators of cardiovascular function, fluid homeostasis and adipocyte endocrine secretion.
