External Ids for APLN Gene
This gene encodes a peptide that functions as an endogenous ligand for the G protein coupled receptor APJ. The encoded protein is synthesized as a prepropeptide that is processed into biologically active C-terminal fragments. The 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 2010]
GeneCards Summary for APLN Gene
APLN (Apelin) is a Protein Coding gene. Diseases associated with APLN include obesity and syndrome of inappropriate antidiuretic hormone. Among its related pathways are Signaling by GPCR and Signaling by GPCR. GO annotations related to this gene include receptor binding and apelin receptor binding.
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), a G-protein-coupled receptor with considerable sequence homology to the angiotensin (AT1) receptor. The APJ receptor and apelin peptides act as mediators of cardiovascular function, fluid homeostasis and adipocyte endocrine secretion.
