基于微导管的马达的 Kinesin 总科安排许多细胞的过程。哺乳动物的染色体的最近的可获得性在整个染色体上启用了 kinesins 的分析。这里我们在场为 mammaliankinesin 基因发现的一个新奇全身的 kinesin 预言节目(FKPP ) 基于比较基因组学来临。与以前的预言 of94 kinesins 相反,我们潜在地识别 134 的一个总数从哺乳动物的染色体的 kinesin 基因,从老鼠的 including45, 45 从老鼠并且 44 从人。另外, FKPP 综合 25 potentiallyfull 长度哺乳动物的 kinesins 基于在数据库的部分序列。令人惊讶地,全身的人的 CENP-E 包含的 FKPPreveals 2701 一一 rather than 2663 一一在里面数据库。试验使用顺序人的 CENP-E 定序的特定的抗体和 cDNA 验证 FKPP 的精确性。给显著计算 FKPP 的效率和精确性,我们重新分类哺乳动物的 kinesin 总科。因为当前的数据库包含许多不完全的序列, FKPP 可以为 kinesins 和另外的蛋白质家庭的分子的描述提供一条新奇途径。
Kinesin superfamily of microtubulebased motor orchestrates a variety of cellular processes. Recent availability of mammalian genomes has enabled analyses of kinesins on the whole genome. Here we present a novel full-length kinesin prediction program (FKPP) for mammalian kinesin gene discovery based on a comparative genomics approach. Contrary to previous predictions of 94 kinesins, we identify a total of 134 potentially kinesin genes from mammalian genomes, including 45 from mouse, 45 from rat and 44 from human. In addition, FKPP synthesizes 25 potentially full-length mammalian kinesins based on the partial sequences in the database. Surprisingly, FKPP reveals that full-length human CENP-E contains 2701 aa rather than 2663 aa in the database. Experimentation using sequence specific antibody and cDNA sequencing of human CENP-E validates the accuracy of FKPP. Given the remarkable computing efficiency and accuracy of FKPP, we reclassify the mammalian kinesin superfamily. Since current databases contain many incomplete sequences, FKPP may provide a novel approach for molecular delineation of kinesins and other protein families.
