果蝇注释基因CG 5155编码一种含有10个Armadillo重复序列的蛋白质,其功能未知。为了填补这一空白,我们使用RNAi进行了功能丧失研究。通过分析四个独立的果蝇RNAi线靶向两个非重叠区域的CG 5155转录本,我们证明,该基因是所需的男性生育力。因此,我们将这个基因命名为Gudu。Gudu的转录本在成年睾丸中高度富集。Gudu基因被一个普遍存在的驱动基因敲除,导致精子细胞成熟所需的个体化复合物形成缺陷,从而损害精子发生。此外,通过将RNAi系与bam-Gal 4驱动子杂交而实现的Gudu的睾丸特异性敲低足以导致不育和精子发生缺陷。由于Gudu与脊椎动物ARMC 4高度同源,ARMC 4也是一种富含睾丸的含有Armadillo重复序列的蛋白质,因此我们的研究结果表明Gudu和ARMC 4是含有Armadillo重复序列的蛋白质的一个亚家族,可能在精子发生中具有进化上保守的功能。
The Drosophila annotated gene CG5155 encodes a protein that contains 10 Armadillo-repeats and has an unknown function. To fill this gap, we performed loss-of-function studies using RNAi. By analysis of four independent Drosophila RNAi lines targeting two non-overlapping regions of the CG5155 transcript, we demonstrate that this gene is required for male fertility. Therefore, we have named this gene Gudu. The transcript of Gudu is highly enriched in adult testes. Knockdown of Gudu by a ubiquitous driver leads to defects in the formation of the individualization complex that is required for spermatid maturation, thereby impairing spermatogenesis. Furthermore, testis-specific knockdown of Gudu by crossing the RNAi lines with the bam-Gal4 driver is sufficient to cause the infertility and defective spermatogenesis. Since Gudu is highly homologous to vertebrate ARMC4, also an Armadillo-repeat-containing protein enriched in testes, our results suggest that Gudu and ARMC4 is a subfamily of Armadillo-repeat containing proteins that may have an evolutionarily conserved function in spermatogenesis.
