A statistical framework for identifying past PRDM9 binding targets in primates

Recombination is a basic biological force, which, with mutation, plays an important role in generating new combinations of alleles in each chromosome, by shuffling and exchanging genetic material between maternal and paternal chromosomes. Multiple lines of evidence suggest that the rapidly evolving...

description Recombination is a basic biological force, which, with mutation, plays an important role in generating new combinations of alleles in each chromosome, by shuffling and exchanging genetic material between maternal and paternal chromosomes.

PRDM9 shows extreme variation in both the number and sequence of its ZFs, between species and amongst individuals, across mammals. The rapid evolution of the PRDM9 ZF array may be a response to escape a self-destructive drive called biased gene conversion, which can cause preferential transmission of hotspot disrupting alleles, and leading to erosion of vital recombination sites – and hotspot signaling motifs – in the genome through time.
