MADS-box

The MADS box is a conserved sequence motif. The genes which contain this motif are called the MADS-box gene family.[1] The MADS box encodes the DNA-binding MADS domain. The MADS domain binds to DNA sequences of high similarity to the motif CC[A/T]6GG termed the CArG-box.[2] MADS-domain proteins are generally transcription factors.[2][3] The length of the MADS-box reported by various researchers varies somewhat, but typical lengths are in the range of 168 to 180 base pairs, i.e. the encoded MADS domain has a length of 56 to 60 amino acids.[4][5][6][7] There is evidence that the MADS domain evolved from a sequence stretch of a type II topoisomerase in a common ancestor of all extant eukaryotes.[8]
