ALG-2 (apoptosis-linked gene 2) is a Ca2+-binding protein that belongs to the PEF (penta-EF-hand) protein family. Alix (ALG-2-interacting protein X)/AIP1 (ALG-2-interacting protein 1), one of its binding partners, interacts with TSG101 and CHMP4 (charged multivesicular body protein 4), which are

Polyphenols (tannins) are known for their high propensity to precipitate proteins. They bind most strongly to proteins with a high proline content. Understanding the mechanism of this association is of prime interest because this interaction might induce protein conformational changes that may

ALG-2 is a Ca(2+)-binding protein that belongs to the penta-EF-hand protein family and associates with several proteins, including annexin VII, annexin XI, and Alix/AIP1, in a Ca(2+)-dependent manner. The yeast two-hybrid system and a biotin-tagged ALG-2 overlay assay were carried out to

The objective of the present investigation was to examine the oral astringency and protein-binding activity of four structurally well-defined tannins, namely, procyanidin [epicatechin16(4-->8)catechin], pentagalloyl glucose (1,2,3,4,6-penta-O-galloyl-beta-D-glucopyranose), castalagin, and grandinin,

The desymmetrization of endo-norborn-5-ene-2,3-dicarboxylic anhydrides by methyl (S)-prolinate followed by ozonolysis of the resulting carboxylic acids is used to prepare enantio- and diastereomerically pure, tetra- and penta-substituted cyclopentane derivatives in which all of the substituents on

ALG-2, a 22-kDa penta-EF-hand protein, is involved in cell death, signal transduction, membrane trafficking, etc., by interacting with various proteins in mammalian cells in a Ca2+-dependent manner. Most known ALG-2-interacting proteins contain proline-rich regions in which either PPYPXnYP (type 1
