Dosage Compensation in Drosophila (Asifa Akhtar)

Published: July 16, 2019, 9:51 a.m.

b'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.\\n\\xa0\\nReferences\\xa0\\nJan Kadlec, Erinc Hallacli, \\u2026 Asifa Akhtar (2011) Structural basis for MOF and MSL3 recruitment into the dosage compensation complex by MSL1 (Nature Structural & Molecular Biology) DOI: 10.1038/nsmb.1960\\xa0\\nThomas Conrad, Florence\\xa0M.G.
