 Nucleotide and deduced amino acid sequences of Laternula elliptica heat shock protein (Hsp) 70 cDNA. The consensus polyadenylation signal (AUUAAA) is double underlined. The characteristic motifs of the Hsp70 family are underlined: three signatures at positions 9–16, 199–206, and 334–339; a putative ATP-GTP binding site at 131–138; a putative bipartite nuclear localization signal at 250–251 and 261–265; and the cytoplasmic Hsp70 carboxyl terminal region at 651–654. The 3′ and 5′ untranslated regions are in lower case. Positions of the probes used in semiquantitative reverse transcriptase–polymerase chain reaction (RT–PCR) to amplify the 97-bp fragment are shown in gray
