感染性朊病毒蛋白由于获得异常构象而导致哺乳动物的神经变性疾病。我们克隆了一个编码结构保守的朊病毒蛋白的红纹东方鲀基因,发现不同脊椎动物类朊病毒之间的分子分化速度很快,沿着每个类内的分子停滞。我们认为,与发病机制和传染性相关的朊病毒序列基序进化的方向性趋势可以解释羊瘙痒病在哺乳动物中的起源。
Infectious prion proteins cause neurodegenerative disease in mammals owing to the acquisition of an aberrant conformation. We cloned aFugu rubripesgene that encodes a structurally conserved prion protein, and found rapid rates of molecular divergence among prions from different vertebrate classes, along with molecular stasis within each class. We propose that a directional trend in the evolution of prion sequence motifs associated with pathogenesis and infectivity could account for the origin of scrapie in mammals.
