'''Structural Genomics of Caenorhabditis elegans: Structure of BAG-1 protein'''<br />


==Overview==
==Overview==
Binding of the BAG domain to the eukaryotic chaperone heat-shock protein, (Hsp70) promotes ATP-dependent release of the protein substrate from, Hsp70. Although the murine and human BAG domains have been shown to form, an antiparallel three-helix bundle, the Caenorhabditis elegans BAG domain, is formed by two antiparallel helices, while the third helix is extended, away and stabilized by crystal-packing interactions. A small beta-sheet, between helices 2 and 3 interferes with formation of the intramolecular, three-helix bundle. However, intermolecular three-helix bundles are, observed throughout the crystal packing and suggest that stable functional, dimers and tetramers can be formed in solution. The structure may, represent a new folding type of the BAG domain.
