Dosage Compensation in Drosophila (Asifa Akhtar)

Dosage compensation is an essential process to regulate the gene expression of the X-chromosome in female and male flies. Thereby the mechanism of regulation in humans and in drosophila is different. In humans one X-chromosome is randomly shut down in females compared to men, whereas in drosophila equilibrium is achieved by overexpression of the single X-chromosome in males. In this Episode our guest Dr. Asifa Akhtar provides information on her work on dosage compensation in drosophila melanogaster and how the MSL-complex, the Histone-acetyltransferase MOF work together in this process. Furthermore, she also talks about potential functions of those Proteins in the human system.
