ELAV(embryonic lethal abnormal visual system,胚胎致死异常视觉系统)/Hu家族蛋白是具有对富含AU的区域的结合偏好的原型RNA结合蛋白。由于在内含子和非翻译区中经常出现富含AU的基序,因此对基因特异性RNA结合蛋白(如ELAV/Hu家族成员)如何在复杂的细胞环境中识别其靶RNA的互补序列知之甚少。果蝇强大的遗传工具使果蝇成为研究发育中生物体内替代mRNA加工的极好模型。最近的12果蝇基因组测序将提供一个新的资源,以提高我们的理解如何基因特异性调控mRNA的加工是通过ELAV/胡家族蛋白。
ELAV (embryonic lethal abnormal visual system)/Hu family proteins are prototype RNA-binding proteins with binding preferences for AU-rich regions. Due to frequent occurrence of AU-rich motifs in introns and untranslated regions, it is poorly understood how gene-specific RNA-binding proteins, such as ELAV/Hu family members, recognize their complement of target RNAs in a complex cellular environment. The powerful genetic tools of Drosophila make the fruitfly an excellent model to study alternative mRNA processing in vivo in a developing organism. Recent sequencing of 12 Drosophila genomes will provide a novel resource to enhance our understanding of how gene-specific regulation of mRNA processing is achieved by ELAV/Hu family proteins.
