Abstract: Heat shock proteins (HSPs) are evolutionally conserved from micro organism to mammals and play important roles in many biological processes including thermal tolerance. We isolated a homologue of small HSP26 (sHSP26) from a subtracted cDNA library of heat shock-treated abalone (Haliotis discus hannai). The abalone sHSP26 encompossed 793 nt, including a coding region of 501 nt. The deduced amino acid sequence of the abalone sHSP26 contained well conserved a-crystallin domain and showed overall identities of 27-31% with the other speciesí sHSP proteins. The abalone sHSP26 transcript was induced by heat shock treatment, but not by cold shock treatment.
Key words: Pacific abalone, Heat shock protein, Small HSP26, Thermal stress
