PA1-005 detects phosphorylated heat shock protein 27 (HSP27) from human and rat tissue samples. This antibody does not detect the unphosphorylated form of the protein.
PA1-005 has been successfully used in Western blot, immunoprecipitation, and immunofluorescence procedures. By Western blot, this antibody detects an ~27 kDa protein representing phosphorylated HSP27(Ser85) from rat skeletal muscle extracts.
The PA1-005 immunogen is a synthetic phosphopeptide corresponding to residues R(82) Q L S(p) S G V S E I R(92) C of rat HSP27. This sequence is completely conserved in mouse.
HSP27 also referred to as the Estrogen-Regulated 24K protein and HSP28, is one of several small heat shock proteins (HSP) produced by all organisms studied. HSP27 synthesis is induced by elevated temperature, as well as estrogen in hormone responsive cells. Interestingly, human HSP27 also shares greater than 50% homology with low molecular weight Drosophila HSP's and mammalian a-crystalline lens protein. Because of the estrogen responsive nature of HSP27, this protein has been studied extensively in human estrogen responsive tissues such as cervix, endometrium and breast tissue. This work has led to the suggestion that HSP27 may be a useful marker in classifying various hormone sensitive tumors.
