Mouse sperm protamine mass spectrometry
Ontology highlight
ABSTRACT: Conventional dogma presumes that protamine-mediated DNA compaction in sperm is achieved by passive electrostatics between DNA and the arginine-rich core of protamines. However, phylogenetic analysis reveals several non-arginine residues that are conserved within, but not across, species. The functional significance of these residues or post-translational modifications are poorly understood. In this experiment, we investigated the presence of post-translational modifications on mouse protamine 1 to begin to dissect their function in vivo.
