The invention discloses epothilone biosynthetic gene transcriptional regulation protein and a preparation method thereof. According to the epothilone biosynthetic gene transcriptional regulation protein and the preparation method thereof, a biotin-labeled epothilone biosynthetic gene promoter P3 fishing method is adopted for the first time to obtain the transcriptional regulation protein of an SOce M4 epothilone biosynthetic gene cluster, and the function of the transcriptional regulation protein is verified by adopting an EMSA experiment. The obtained novel epothilone biosynthetic gene cluster transcriptional regulation protein can lay a molecular biological foundation for the biosynthetic transcriptional regulation of sprangium cellulosum epothilone and the heterologous expression of the epothilone biosynthetic gene cluster, and therefore the efficient biosynthesis of the epothilone and the wide application of the epothilone in the aspect of biological medicine are promoted.

The present invention relates to the use of natural or synthetic Epothilones for the treatment prevention or alleviation of diseases caused by a dysbalance of osteoclast and osteoblast activity, especially osteoporosis.

Epothilone analogues include a molecular scaffold which holds at least one segment of epothilone in a predetermined orientation and which rigidities a region between the macrolactone ring and the aromatic side-chain.

The invention discloses a novel epothilone biosynthetic gene P3 promoter as well as a preparation method and application thereof. A nucleotide sequence of the P3 promoter is shown as SEQ ID NO. 1. Thepromoter of a So ce M4 epothilone biosynthetic gene is amplified by adopting a degenerate primer designing method for the first time; the promoter is subjected to cloning and promoter element analysis; and a luciferase reporter gene vector is adopted to verify the functions of the obtained epothilone biosynthetic gene promoter. The obtained novel epothilone biosynthetic gene cluster promoter canlay a molecular biological foundation for transcriptional regulation of sprangium cellulosum epothilone biosynthesis and heterologous expression of an epothilone biosynthetic gene cluster; the improvement of the yield of epothilone is promoted; and wide application of the epothilone in the aspect of biomedicines is promoted.
