General description
Human gelsolin (also known as brevin) is an actin severing protein found in mammalian cells and blood plasma. Gelsolins consist of a 730 amino acid core structure which contains six repeated domains. These six domains make up three distinct actin binding sites. The plasma enzyme contains an N-terminal extension of 25 amino acids that raises its molecular weight from 90 kD to 93 kD.
Application
Plasma gelsolin levels may be used to identify patients at risk for increased morbidity.
Biochem/physiol Actions
Gelsolin is an actin-binding protein that regulates the assembly and disassembly of actin filaments.
Gelsolin is an actin-severing protein found in mammalian cells and blood plasma. Exhibits tumor suppressor activity in several cancer cell lines and in nude mice.

To examine the relationship between plasma gelsolin levels and mortality following surgery or trauma. Few simple predictive diagnostic tests are available to predict mortality following surgery or trauma. We hypothesize that plasma concentrations of gelsolin, a protein that responds to

The plasma level of LPA (lysophosphatidic acid) (200-600 nM) is well within the range that promotes proliferation and migration of vascular ECs (endothelial cells), yet vessels are quiescent and stable. In this report, we considered one explanation for this paradox:

Summary Successful malaria transmission from the mosquito vector to the mammalian host depends crucially on active sporozoite motility. Sporozoite locomotion and host cell invasion are driven by the parasite's own actin/myosin motor. A unique feature of this motor machinery is
