NCIt definition : Apelin (77 aa, 9 kDa) is encoded by the human APLN gene. This protein is involved
in both the inhibition of HIV-1 entry into cells and in immune responses.;
NCIt note : Apelin is a precursor to at least four active peptides that are produced by proteolytic
processing of the full length gene product. These active peptides include Apelin-36,
Apelin-31, Apelin-28 and Apelin-13. (UniProt);
