<p>which marks proteins for degradation, also has features of a heat shock protein. A conserved protein binding domain of approximately 80 amino-acid alpha crystallins are known as small heat shock proteins (sHSP).</p>

<p>It is known that rapid heat hardening can be elicited by a brief exposure of cells to sub-lethal high temperature, which in turn provides protection from subsequent and more severe temperature. In 1962, Italian geneticist <a href="page.php?w=Ferruccio_Ritossa">Ferruccio Ritossa</a> reported that heat and the</p><p>
