Functional validation of hydrophobic adaptation to physiological temperature in the small heat shock protein αA-crystallin. by Mason Posner, Andor J Kiss, Jackie Skiba, Amy Drossman, Monika B Dolinska, J Fielding Hejtmancik, Yuri V Sergeev

“…Here we used recombinant protein of the lenticular sHsp α A-crystallin from six teleost fishes environmentally adapted to temperatures ranging from -2°C to 40°C to identify correlations between physiological temperature, protein stability and chaperone-like activity. Using sequence and structural modeling analysis we identified specific amino acid differences between the warm adapted zebrafish and cold adapted Antarctic toothfish that could contribute to these correlations and validated the functional consequences of three specific hydrophobicity-altering amino acid substitutions in αA-crystallin. …”
