The Erica Larschan Lab
Dosage Compensation in Drosophila melanogaster

How are genes precisely regulated throughout development to prevent disease? We study Drosophila dosage compensation to understand how chromatin domains form within the nucleus and function to spatially and temporally regulate genes.

{{content.about.headerOne}}

Drosophila dosage compensation targets the male X chromosome.

{{content.about.headerTwo}}

The speed of RNA Polymerase may be increased in the presence of the MSL Complex, suggesting a mechanism for upregulation.
