Eukaryotic ribosomes contain one molecule each of 79 different proteins. The genes encoding these proteins are usually at widely scattered loci and have distinctive promoters with certain common features. This minireview discusses the means by which cells manage to balance the production of ribosomal proteins so as to end up with equimolar quantities in the ribosome. Regulation at all levels of gene expression, from transcription to protein turnover, is considered.
真核生物核糖体包含79种不同蛋白质,每种各一个分子。编码这些蛋白质的基因通常位于广泛分散的基因座上,并且具有带有某些共同特征的独特启动子。本综述讨论了细胞平衡核糖体蛋白产量以便在核糖体中最终获得等摩尔量的方式。从转录到蛋白质周转,基因表达各个水平的调控都在考虑范围内。
