title: Preparation and characterization of pig plasma and platelet gelsolins.
abstract: Pig plasma gelsolin has been prepared by a revised method involving poly(ethylene glycol) precipitation, chromatography on CM-cellulose and affinity chromatography on actin-Sepharose. Pig platelet gelsolin has been prepared by chromatography on DEAE-cellulose and actin-Sepharose. Partial chemical and proteolytic cleavage shows that the two proteins are closely related in their fragmentation patterns. The amino acid sequences are identical at the N-terminus of the platelet protein, but the plasma protein has an additional nine residues on the N-terminal side of the common sequence. Calcium binding studies show that the plasma protein has similar calcium binding properties to both macrophage and platelet gelsolins.
