摘要: MIKC型蛋白是植物中特有的一类MADS-box转录因子, 具有一个独特的结构域。除了高度保守的MADS域外, 还包括3个其他的域(I、K和 C)。植物进化过程中, MIKC型蛋白的数量和功能多样化不断增加, 在高等开花植物中达到顶峰。它们在花发育的不同阶段发挥了重要的调控作用。综述了植物MIKC型MADS蛋白的分类及结构, 与DNA的相互作用, 蛋白之间相互作用及其分子机制, 并对MIKC型蛋白的深入研究进行了展望。

Abstract: MIKC-type proteins represent a class of MADS-domain transcription factors in plant and are defined by a unique domain structure. In addition to the highly conserved MADS-domain, they have three other domains(I, K and C). The number and functional diversity of MIKC-type proteins increased considerably during plant evolution, culminating in higher flowering plants. They are known to play key regulatory roles in different stages of flower development. This paper summarized the plant MIKC-type MADS protein classification and structure, interactions with DNA, interactions between proteins and molecular mechanism of the interactions. It also discusses about the prospects of future research works, according to the present research status on MIKC-type proteins.

Key words: MIKC-type MADS proteins, Interactions, Transcription factors
