| Abstract |
Various sorts of bioactive molecules including hormones, neurotransmitters, and chemokines transmit signals into cells by binding to so-called seven-transmembrane-domain receptors (7TMRs). The recent progress in cDNA and genome DNA analyses has brought the discovery of numerous genes encoding ligand-unknown "orphan" 7TMRs. We have developed a strategy to identify the ligands of orphan 7TMRs by monitoring specific signal transductions induced in cells expressing orphan 7TMRs. Employing this method, we succeeded in identifying the natural ligands of the orphan 7TMRs, hGR3, and APJ. The ligand peptide identified for hGR3 was found to show a specific prolactin release promoting activity in rat anterior pituitary cells in in vitro culture and was therefore named "prolactin-releasing peptide." We named another novel bioactive peptide "apelin," for "APJ endogenous ligand." Although the biological functions of apelin are still under investigation, APJ reportedly acts as a coreceptor in the process of human immunodeficiency virus infection. We believe that the identification of orphan 7TMR ligands will provide clues to reveal the unknown regulatory mechanisms of various physiological phenomena and opportunities for novel drug discovery in the future. |

Attention Score in Context
This research output has an Altmetric Attention Score of 6. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 23 April 2019.
All research outputs
#5,447,195
of 25,374,917 outputs
Outputs from Journal of Molecular Medicine
#311
of 2,137 outputs
Outputs of similar age
#5,321
of 34,930 outputs
Outputs of similar age from Journal of Molecular Medicine
#2
of 9 outputs
Altmetric has tracked 25,374,917 research outputs across all sources so far. Compared to these this one has done well and is in the 75th percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 2,137 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.3. This one has done well, scoring higher than 77% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 34,930 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 71% of its contemporaries.
We're also able to compare this research output to 9 others from the same source and published within six weeks on either side of this one. This one has scored higher than 7 of them.
