What is another name for protamine?

Published in Biochemistry 1 min read

Another name for protamine, particularly the protamine derived from salmon, is salmine.

Understanding Salmine: A Specific Type of Protamine

Salmine is a historically significant type of protamine primarily extracted from the sperm of salmon. It was identified early on and is well-characterized for its properties.

  • Extraction Process: Salmine can be extracted using hydrochloric acid.
  • Precipitation: It can be precipitated with substances like platinum chloride.
  • Composition: Salmine constitutes a substantial portion, approximately 26.8%, of the dried sperm from which it is derived.

Broader Applications of Protamine

While "salmine" refers specifically to salmon protamine, the broader term "protamine" encompasses a group of highly cationic proteins found in sperm. These proteins play a crucial role in condensing DNA within the sperm head. Beyond their biological function, protamines have significant medical applications, most notably in the form of protamine sulfate.

  • Medical Use: Protamine sulfate gained approval for medical use in 1969.
  • Therapeutic Role: It is commonly used to reverse the anticoagulant effects of heparin, for instance, after surgery or dialysis.
  • Modern Production: Today, the majority of protamine used for medical purposes is manufactured using advanced recombinant biotechnology techniques, ensuring a consistent and reliable supply.
