CST, 15429C, FastScan™ Phospho-HSP27 (Ser82) ELISA Kit

Protocol
Available protocols: ELISA+
Specificity / Sensitivity
The FastScan™ Phospho-HSP27 (Ser82) ELISA Kit detects endogenous levels of HSP27 when phosphorylated at Ser82 as shown in Figure 1. This kit detects proteins from the indicated species, as determined through in-house testing, but may also detect homologous proteins from other species.
Species Reactivity: Human, Monkey
Background
Heat shock protein (HSP) 27 is one of the small HSPs that are constitutively expressed at different levels in various cell types and tissues. Like other small HSPs, HSP27 is regulated at both the transcriptional and posttranslational levels (1). In response to stress, the HSP27 expression increases several-fold to confer cellular resistance to the adverse environmental change. HSP27 is phosphorylated at Ser15, Ser78, and Ser82 by MAPKAPK-2 as a result of the activation of the p38 MAP kinase pathway (2,3). Phosphorylation of HSP27 causes a change in its tertiary structure, which shifts from large homotypic multimers to dimers and monomers (4). It has been shown that phosphorylation and increased concentration of HSP27 modulates actin polymerization and reorganization (5,6).
