1. Protamine

   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. They may allow for denser packaging of DNA in the spermatozoon than histones, but they must be decompressed before the genetic data can be used for protein synthesis. However, in humans and maybe other primates, 10-15% of the sperm's genome is packaged by histones thought to bind genes that are essential for early embryonic development.Protamine and protamine-like (PL) proteins are collectively known as the sperm-specific nuclear basic proteins (SNBPs). The PL proteins are intermediate in structure between protamine and Histone H1. The C-terminal domain of PL could be the precursor of vertebrate protamine.

1. protamine

   Protamine is a group of small, positively charged proteins that are associated with sperm DNA. They play a key role in the packaging of sperm DNA and are known for their arginine-rich content. Medically, they are used to neutralize the anticoagulant effect of heparin in the treatment of conditions like hemophilia and kidney dialysis. It's also used in manufacturing certain types of insulin.
