Allelic Expression of Drosophila Protamines during Spermatogenesis
In typical somatic cells, DNA is tightly organized by histones that are necessary for its proper packaging into the nucleus. In sexually-reproducing animals, the haploid product of male meiosis must be further condensed to fit within sperm heads, thus requiring an even greater degree of packaging. This is accomplished in most organisms by replacing histones with protamines, which allows DNA to ...
متن کاملProtamines and spermatogenesis in Drosophila and Homo sapiens
The production of mature and motile sperm is a detailed process that utilizes many molecular players to ensure the faithful execution of spermatogenesis. In most species that have been examined, spermatogenesis begins with a single cell that undergoes dramatic transformation, culminating with the hypercompaction of DNA into the sperm head by replacing histones with protamines. Precise execution...
متن کاملTranscriptional regulation during Drosophila spermatogenesis
Drosophila spermatogenesis has become a paradigmatic system for the study of mechanisms that regulate adult stem cell maintenance, proliferation and differentiation. The dramatic cellular differentiation process from germline stem cell (GSC) to mature sperm is accompanied by dynamic changes in gene expression, which are regulated at transcriptional, post-transcriptional (including translational...
متن کاملX Chromosome Inactivation during Drosophila Spermatogenesis
Genes with male- and testis-enriched expression are under-represented on the Drosophila melanogaster X chromosome. There is also an excess of retrotransposed genes, many of which are expressed in testis, that have "escaped" the X chromosome and moved to the autosomes. It has been proposed that inactivation of the X chromosome during spermatogenesis contributes to these patterns: genes with a be...
متن کاملMolecular mechanisms of gene regulation during Drosophila spermatogenesis.
The differentiation of sperm from morphologically unremarkable cells into highly specialised free-living, motile cells requires the co-ordinated action of a very large number of gene products. The expression of these products must be regulated in a developmental context to ensure normal cellular differentiation. Many genes essential for spermatogenesis are not used elsewhere in the animal, or a...
