Protamines are small, arginine-rich, nuclear proteins that replace histones late in the haploid phase of spermatogenesis and are believed essential for sperm head condensation and DNA stabilization. It may allow for denser packaging of DNA in spermatozoon than histones, but it must be decompressed before the genetic data can be used for protein synthesis. Genes that are essential for early embryonic development are still bound to ordinary histones, comprising about 4 percent of the DNA in spermatozoons.
