Abstract

Mutations in the Caenorhabditis elegans RNA polymerase II AMA-1/RPB-1 subunit that cause α-amanitin resistance and/or developmental defects were isolated previously. We identified 12 of these mutations and mapped them onto the Saccharomyces cerevisiae RPB1 structure to provide insight into AMA-1 regions that are essential for development in a multicellular organism.

摘要

先前已经分离出导致 α-鹅膏蕈碱抗性和/或发育缺陷的秀丽隐杆线虫 RNA 聚合酶 II AMA-1/RPB-1 亚基突变。我们鉴定了其中的 12 个突变,并将它们映射到酿酒酵母 RPB1 结构上,以深入了解 AMA-1 区域在多细胞生物发育中必不可少的部分。
