热休克蛋白（heatshockprotein，HSP）是细胞或机体在应激条件下表达的一类进化上高度保守的蛋白质。HSPgO有a和p两种拷贝，其基因是HSP家族中为数不多的含有内含子的成员。HSP90在人体大部分细胞中呈组成性表达，同时还受热诱导表达。本组曾用氯霉素乙酸基转移酶（CAT）报告基 Heat shock protein (HSP) is a class of evolutionarily conserved proteins expressed by cells or tissues under stress conditions. HSPgO has both a and p copies, and its gene is one of the few intron-containing members of the HSP family. HSP90 is constitutively expressed in most human cells and is also induced by heat. This group had chloramphenicol acetyl transferase (CAT) reporter
