At least four different classes of cell cycle regulated gene exist in yeast: G1 cyclins and DNA synthesis genes are expressed in late G1; histone genes in S phase; genes for transcription factors, cell cycle regulators and replication initiation proteins in G2; and genes needed for cell separation as cells enter G1. Early and late G1-specific transcription is mediated by the Swi5/Ace2 and Swi4/Swi6 classes of factor, respectively. Changes in cyclin/Cdc28 kinases may be involved in all classes of regulation. Transcriptional control of cyclin genes has an important role in regulating cell cycle progression.
G1 期周期蛋白和 DNA 合成基因在 G1 晚期表达;组蛋白基因在 S 期表达;转录因子、细胞周期调节因子和复制起始蛋白的基因在 G2 期表达;而细胞进入 G1 期时细胞分离所需的基因表达。G1 早期和晚期特异性转录分别由 Swi5/Ace2 和 Swi4/Swi6 类因子介导。周期蛋白/Cdc28 激酶的变化可能参与所有类型的调控。周期蛋白基因的转录控制在调节细胞周期进程中起着重要作用。
