我们描述了肌球蛋白基因MYH16的分子进化模式,使用来自黑猩猩和人类基因组测序项目的超过30,000 bp的外显子和内含子序列数据来评估人类谱系特异性移码缺失的时间和后果。我们估计缺失的年龄约为5.3 MYA。这一估计与人类和黑猩猩分化的时间一致,比化石记录中首次出现的人属要早得多。我们还发现了该基因不同区域的非同义固定率(d(N))的相互矛盾的估计,揭示了与人类MYH16假基因进化的简单模型不一致的复杂模式。
We describe the pattern of molecular evolution at a sarcomeric myosin gene, MYH16, using more than 30,000 bp of exon and intron sequence data from the chimpanzee and human genome sequencing projects to evaluate the timing and consequences of a human lineage-specific frameshift deletion. We estimate the age of the deletion at approximately 5.3 MYA. This estimate is consistent with the time of human and chimpanzee divergence and is significantly older than the first appearance of the genus Homo in the fossil record. We also find conflicting estimates of nonsynonymous fixation rates (d(N)) across different regions of this gene, revealing a complex pattern inconsistent with a simple model of pseudogene evolution for human MYH16.
