Summary: 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]

Envelope surface glycoprotein gp120	env	APJ, a seven transmembrane domain G-protein-coupled receptor, functions as a coreceptor for gp120 from some HIV-1 strains; a natural peptide ligand for APJ, apelin-13, efficiently blocks APJ coreceptor activity	PubMed
	env	Macrophage-tropic HIV-1 can use CCR2b, and to a lesser extent CCR3, STRL33, and APJ, to infect cells; the V1/2 region of HIV-1 gp120 plays a more important role in governing the use of CCR2b, CCR3, STRL33, and APJ than for CXCR4	PubMed

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

NR_027991.2 RNA Sequence

Status: REVIEWED

Description

Transcript Variant: This variant (2) lacks an alternate internal segment, compared to variant 1. This variant is represented as non-coding because the use of the 5'-most supported translational start codon, as used in variant 1, renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
