Addition of antiserum specific to cam to a whole cell extract reduced binding of the hsf to hse at 44 . re - addition of cam to the cell extract pretreated with antiserum might restore the ability of the hsf to bind to hse . dna - binding activity of the hsf was promoted by directly adding cam to a whole cell extract at 44 , but not by the same concentration of s100 and bsa 兔抗cam血清也明顯抑制44熱激誘導的hsf的dna結合活性,而回加cam又可恢復其活性;熱激條件下直接以cam處理可促進hsf的dna結合活性,同樣濃度的s - 100和bsa無明顯作用;另外,在非熱激條件下外加cam還可替代熱激誘導hsf的dna結合活性,而同樣濃度的bsa處理無此作用。
