Abstract
The regulation of gene expression clearly pivotal in differentiation of specific cell types. Sperm are arguably the most specialised of all animal cells, and their production requires the expression of a very large number of genes not expressed in any other process. Notably, expression of about 10% of all protein coding genes is specific to, or highly enriched in, testes. We use Drosophila testes as a model to understand how this specialised gene expression programme is controlled.
I will discuss our work describing the testis-specific transcriptional regulator, tMAC, notably, what are the components of this complex, and how to they work together to regulate target genes. I will present recent data indicating that the RNA export pathway is also implicated in activation of testis-specific gene expression, through an interaction with tMAC. Finally I will discuss a new approach we are using to directly determine the chromatin environment at a genome scale in primary spermatocytes.
