Abstract

Significance: It was previously believed that placental mammals present no variability in oxytocin (OXT). The present study reports novel data on the diversity of OXT and its receptor ( OXTR ) in primate species, including New World monkeys. Contrary to prior expectations, we found three novel OXT forms and several OXTR nonsynonymous changes not previously described. In the Cebidae family, signals of positive selection were found for an OXT variant at position 8, which is associated with larger litter sizes. We detected positive selection for OXTR forms and report a coevolutionary process between changes in OXT and OXTR.

  • New World monkeys have genetic variation in OT and AVP peptide and receptor genes across species.

    “Species differences in receptor binding characteristics vary widely, especially in light of recent discoveries in New World monkeys, which show genetic variations in both the OT and AVP peptide and receptor genes across species (105-110).”
  • Receptor binding characteristics differ widely across species.

    “Species differences in receptor binding characteristics vary widely, especially in light of recent discoveries in New World monkeys, which show genetic variations in both the OT and AVP peptide and receptor genes across species (105-110).”
  • Recent discoveries have identified surprising variability in OT and peptide structure in New World monkeys (NWM), with five new OT variants identified to date.

  • The prevalence of nonsynonymous substitutions in OXT in every genus of New World monkeys codes for five distinct forms of OT in addition to consensus mammalian Leu8-OT, for a total of six OT ligand variants in this taxon.

    “The feature that stands out most prominently is the prevalence of NSs in OXT in every genus of NWM, which in turn code for five distinct forms of OT in addition to consensus mammalian Leu8-OT, for a total of six OT ligand variants in this taxon.”

  • Some species of Saguinus possess a second nonsynonymous substitution at the 3rd position (ATC to GTC), producing a residue substitution of isoleucine to valine, yielding Val3-Pro8-OT.

    “some species of Saguinus also possess at second NS at the 3rd position (ATC → GTC), producing a residue substitution of isoleucine → valine, yielding Val3-Pro8-OT.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
