We have cloned and determined the nucleotide sequence of a mouse lamin A cDNA. The clone contained the C-terminal two-thirds of the lamin A coding sequence and a 3' untranslated sequence with a poly(A) stretch. As has been reported for human lamin A/C cDNAs, a large part of the 5' sequence of our mouse lamin A clone was essentially identical with a previously reported mouse lamin C cDNA sequence, and the deduced C-terminal amino acid sequence shared strong homology with the human lamin A sequence. A putative deduced amino acid sequence for mouse lamin A, which was derived from our sequence and the published lamin C sequence, was 665 amino acids long. The degree of overall homology to the human sequence was more than 95%, and relatively more variation was scattered in the C-terminal lamin A-specific region.
我们克隆并测定了小鼠核纤层蛋白A cDNA的核苷酸序列。该克隆包含核纤层蛋白A编码序列的C端三分之二以及带有poly(A)序列的3'非翻译序列。正如已报道的人类核纤层蛋白A/C cDNA一样,我们的小鼠核纤层蛋白A克隆的5'序列大部分与先前报道的小鼠核纤层蛋白C cDNA序列基本相同,并且推导的C端氨基酸序列与人类核纤层蛋白A序列具有很强的同源性。从小鼠核纤层蛋白A的推测推导氨基酸序列(该序列来自我们测定的序列和已发表的核纤层蛋白C序列)长665个氨基酸。与人类序列的总体同源性程度超过95%,并且相对更多的变异分散在C端核纤层蛋白A特异性区域。
