在过去的25年里,对果蝇糖蛋白聚糖的多样性和功能的认识取得了重大进展。遗传筛选已经捕获了突变,这些突变揭示了由聚糖调节的重要生物活性,包括蛋白质折叠和运输,以及细胞信号传导,组织形态发生,生育力和活力。许多这些聚糖功能在脊椎动物的发育和疾病中有相似之处,这为利用果蝇遗传学来剖析病理机制提供了越来越多的机会。结构分析技术的灵敏度的进步,允许野生型和突变体组织的聚糖档案进行评估,揭示新的聚糖结构,可能是功能上类似于脊椎动物聚糖。本文综述了果蝇N-连接和O-连接(非糖胺聚糖)糖蛋白聚糖的功能,重点是它们与脊椎动物生物体的相关性的最新进展。
The past 25 years have seen significant advances in understanding the diversity and functions of glycoprotein glycans in Drosophila melanogaster. Genetic screens have captured mutations that reveal important biological activities modulated by glycans, including protein folding and trafficking, as well as cell signaling, tissue morphogenesis, fertility, and viability. Many of these glycan functions have parallels in vertebrate development and disease, providing increasing opportunities to dissect pathologic mechanisms using Drosophila genetics. Advances in the sensitivity of structural analytic techniques have allowed the glycan profiles of wild-type and mutant tissues to be assessed, revealing novel glycan structures that may be functionally analogous to vertebrate glycans. This review describes a selected set of recent advances in understanding the functions of N-linked and O-linked (non-glycosaminoglycan) glycoprotein glycans in Drosophila with emphasis on their relatedness to vertebrate organisms.
