Scientific Background: HSP70 genes encode abundant heat-inducible 70-kDa HSPs (HSP70s). In most eukaryotes HSP70 genes exist as part of a multigene family (1). They are found in most cellular compartments of eukaryotes including nuclei, mitochondria, chloroplasts, the endoplasmic reticulum and the cytosol, as well as in bacteria. It assists in protein folding, stabilizes unfolded proteins to prevent aggregation, and handles misfolded proteins under stress conditions. Hsp70 is crucial for cellular repair, aiding in translocation and acting as an anti-apoptotic agent. The HSP70 genes show a high degree of conservation, having at least 5O% identity (2). The proteins features an N-terminal nucleotide-binding domain (NBD) and a C-terminal substrate-binding domain (SBD). The N-terminal two thirds of HSP70s are more conserved than the C-terminal third. HSP70 binds ATP with high affinity and possesses a weak ATPase activity which can be stimulated by binding to unfolded proteins and synthetic peptides (3). They use ATP hydrolysis to bind (ADP-bound) and release (ATP-bound) substrates, aiding in their folding. When HSC70 (constitutively expressed) present in mammalian cells was truncated, ATP binding activity was found to reside in an N-terminal fragment of 44 kDa which lacked peptide binding capacity. Their polypeptide binding ability resides within the C-terminal half, and they bind to hydrophobic regions of unfolded proteins (4). The structure of this ATP binding domain displays multiple features of nucleotide binding proteins (5). All HSP70s, regardless of location, bind proteins, particularly unfolded ones. The binding of ATP triggers a critical conformational change leading to the release of the bound substrate protein (6). The universal ability of HSP70s to undergo cycles of binding to and release from hydrophobic stretches of partially unfolded proteins determines their role in a great variety of vital intracellular functions such as protein synthesis, protein folding and oligomerization and protein transport.
