Figure 8From: An enigmatic fourth runt domain gene in the fugu genome: ancestral gene loss versus accelerated evolutionThe hypothesized recombination event between the ancestral RUNX2A and RUNT genes. After the recombination, the RUNT gene is linked to SUPT3H and has a RUNX2-like first exon. The derivative RUNX2A gene has not yet been observed in pufferfishes, and may have been lost in evolution.Back to article page
