SummaryPituitary growth hormone and prolactin, together with the homologous placental hormones, comprise a family of related protein hormones. Complete or partial amino acid sequences of seven mammalian growth hormones, six mammalian prolactins and one placental lactogen are available, and have been compared. A phylogenetic tree has been constructed which describes the relationships within the family. At least two gene duplications have occurred during the evolution of these proteins. Rates of…

Do some viruses use growth hormone, prolactin and their receptors to facilitate entry into cells?

TLDR
The hypothesis implies that the extensive changes introduced into growth hormone, prolactin and their receptors during the course of mammalian evolution reflect viral interactions, not endocrine adaptations.
Molecular Evolution of Prolactin in Primates
TLDR
The observations that the rate of evolution slowed toward the basal rate after this burst of rapid evolution, and the distribution of substitutions in the prolactin molecule is very uneven support the idea that this episode of rapid change was due to positive adaptive selection.

Similarities and Differences Among Prolactins and Growth Hormones and Their Receptors 1
TLDR
It is proposed that the receptor binding domains of PRL and GH were present in their common ancestral gene and that they have been retained to variable degrees by all of the descendant members of the PRL-GH family.
Duplication of accelerated evolution and growth hormone gene in passerine birds.
TLDR
Comparisons of the nonsynonymous/synonymous substitution ratios and the rate of predicted amino acid changes indicate that the 2 gene duplicates are evolving under different selective pressures and may be functionally divergent.

TLDR
Detailed analysis of evolutionary rates, and other factors, indicates that the episode of rapid change in hyrax, and probably elephant, was adaptive, though the nature of the associated biological change(s) is not clear.
Episodic Molecular Evolution of Some Protein Hormones in Primates and Its Implications for Primate Adaptation
TLDR
A large number of speciation events occurred during the course of primate evolution since the initial radiation of plesiadapiforms in the Paleocene (Fleagle, 1999).
Remarkably high rate of molecular evolution of ruminant placental lactogens
  • M. Wallis

  • 2004
TLDR
Analysis of the cDNA sequences indicates that the rate of nonsynonymous substitution in these proteins is considerably greater than the rates of synonymous substitution, which suggests that the observed rapid rate of evolution is due to incorporation of adaptive rather than neutral mutations.

TLDR
A high degree of homology exists between the known structure of ovine prolactin and the porcine lactogenic hormone, which led to a re-examination of residues 82-90 in the ovine Prolactin structure, where an extra leucine was found in position 88.

TLDR
The data reported predict the previously unknown sequence of the signal peptide of human growth hormone and strengthens the hypothesis that these genes evolved by gene duplication from a common ancestral sequence.
