Allgemeine Beschreibung

Protamines are proteins rich in cysteine and arginine. It possesses many phosphorylation sites. Salmon fish contains around 15 genes encoding protamine. It is found to be localized to the sperm head.

Anwendung

Protamine from salmon has been used to avoid in vitro AT complex formation in samples from dogs pre-treated with heparin. It has also been used to study the influences of external potential on adsorption of various proteins to a metal surface.

Biochem./physiol. Wirkung

Protamine in the form of solid lipid nanoparticles (SLN) promoted transfection with plasmid DNA more efficiently and with less cytotoxicity than comparable SLNs composed of Esterquat-1.
Protamines are found to displace histones in DNA during spermatogenesis in animals and plants. Protamine is useful as a heparin neutralizer during heart surgery, dialysis and in many other clinical procedures.

DNA looping plays an important role in cells in both regulating and protecting the genome. Often, studies of looping focus on looping by prokaryotic transcription factors like lac repressor or by structural maintenance of chromosomes proteins such as condensin. Here

Due to their capability to transport chemicals or proteins into target cells, cell-penetrating peptides (CPPs) are being developed as therapy delivery tools. However, and despite their interesting properties, arginine-rich CPPs often show toxicity for reasons that remain poorly understood. Using
