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
