High impact information on Catarrhini

  • The pattern of substitutions at the DRB loci of most Catarrhini species indicates constant positive selection at ARS codons over the evolutionary period examined [1].
  • The eight or nine genes of the DRB region were also generated in the ancestral Catarrhini, but the region has since been subject to frequent rearrangements, which generated various DRB haplotypes [2].
  • The duplication that generated the two C4-CYP21 modules occurred in the ancestral Catarrhini or earlier, but the region has been undergoing periodic homogenizations via unequal crossing-over, which make paralogous genes in the same species more similar to each other than to orthologous genes of different species [2].
  • Six Aotus MHC class I sequence groups (Ao-g1, Ao-g2, Ao-g3, Ao-g4, Ao-g5 and Ao-g6) weakly related to non-classical Catarrhini MHC were identified [3].
  • Alpha1 and alpha2 domains of Aotus MHC class I and Catarrhini MHC class Ia share similar characteristics [4].
 

Biological context of Catarrhini

  • These results are consistent with the view that the human class I ADH gene cluster has been generated through gene multiplication events which occurred before the Catarrhini branch point in the course of primate evolution [5].
  • Comparison of Platyrrhini and Catarrhini CCR5 consensus sequences evidenced several amino acid residues that differ between both groups, some of which have been experimentally associated with lentiviral interaction [6].
 

Associations of Catarrhini with chemical compounds

  • Both the total and free thyroid hormone concentrations in catarrhini and prosimiae were similar to those in human [7].
  • It is hypothesised that following the divergence of the Platyrrhini lineage from Catarrhini, the LH/CG system evolved independently with ancestral functions of the LH/CG system retained in the neotropical taxa [8].
  • Thyroxine(T4)-binding to serum proteins in primates; catarrhini, prosimiae, and platyrrhini were studied by polyacrylamide gel electrophoresis T4 binding analysis [7].
 

Gene context of Catarrhini

  • Platyrrhini CCR5 genes were shown to be more genetically diverse than their Catarrhini correlates, and their phylogenetic relationships based on that locus were in agreement with previous studies [6].
  • The anti-human transcortin antibody was recognized by plasma proteins obtained from Catarrhini, taxonomically the most evolved monkey group [9].
  • T4-binding analysis also revealed that catarrhini and prosimiae have a high affinity T4-binding protein similar to human TBG [7].
