Virol. 74:11972-11976(2000). CC -!- FUNCTION: Endogenous ligand for APJ, an alternative coreceptor CC with CD4 for HIV-1 infection. Inhibits HIV-1 entry in cells CC coexpressing CD4 and APJ. Apelin-36 has a greater inhibitory CC activity on HIV infection than other synthetic apelin derivatives. CC The oral intake in the colostrum and the milk could have a role in CC the modulation of the immune responses in neonates. May also have CC a role in the central control of body fluid homeostasis by CC influencing AVP release and drinking behavior. CC -!- SUBCELLULAR LOCATION: Secreted. CC -!- TISSUE SPECIFICITY: Expressed in the brain with highest levels in CC the frontal cortex, thalamus, hypothalamus and midbrain. Secreted CC by the mammary gland into the colostrum and the milk. CC -!- PTM: Several active peptides may be produced by proteolytic CC processing of the peptide precursor. CC -!- SIMILARITY: Belongs to the apelin family.
