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.
Function
When mixed with insulin, protamines slow down the onset and increase the duration of insulin action (see NPH insulin).
Protamine sulfate is an antidote for heparin.
Examples
Mice, humans, and certain fish have 2 or more different protamines, whereas the sperm of bull, boar, rat, rabbit, guinea pig, and ram have one form of protamine.
Human
The 2 human protamines are denoted PRM1 and PRM2.
