Abstract

Despite being bilaterally symmetric, most Metazoa exhibit clear, genetically determined left-right differences. In several animals, microtubule-based structures are thought to be the source of chiral information used to establish handedness. Now, two new studies in Drosophila identify a role for unconventional myosin motors in this process.

摘要

尽管大多数后生动物具有双侧对称性，但它们仍表现出明显的、由基因决定的左右差异。在几种动物中，基于微管的结构被认为是用于建立手性的手性信息来源。现在，两项关于果蝇的新研究确定了非常规肌球蛋白马达在这一过程中的作用。
