Drive Against Hotspot Motifs in Primates Implicates the PRDM9 Gene in Meiotic Recombination

Abstract: Although present in both humans and chimpanzees, recombination hotspots, at which meiotic crossover events cluster, differ markedly in their genomic location between the species. We report that a 13-base pair sequence motif previously associated with the activity of 40% of human hotspots does not function in chimpanzees and is being removed by self-destructive drive in the human lineage. Multiple lines of evidence suggest that the rapidly evolving zinc-finger protein PRDM9 binds to this motif and that sequence… Show more

“…Whether additional chromatin factors (beyond DNA sequence) serve to recruit Prdm9 to hotspots also remains unknown. Interestingly, hotspots strongly affect the inheritance of specific sequences, as their tendency to undergo gene conversion drives their removal from the genome [98].…”

“…6,7 Moreover, PRDM1, a zinc-finger containing H3K4 histone methyltransferase, has been identified as a mammalian hotspot-associated protein. [8][9][10] In this study, Wagner and colleagues show that histone 2A lysine acetylation (H2AK5ac) levels are elevated in xnd-1 mutants, suggesting that xnd-1 may regulate this acetylation site. Moreover, they propose that the H2AK5ac mark may be a crucial new regulator of meiotic COs in C. elegans.…”

“…Les travaux présentés ci-dessus montrent que la position d'une fraction importante des crossing-over est [9]. L'étude de PRDM9 a permis de mettre en évidence une évolution extrêmement rapide de ses doigts de zinc qui concerne essentiellement les acides aminés impliqués dans la spécificité des séquences d'ADN reconnues [11].…”
