Abstract
The FK506-binding protein 51 (FKBP51) is an important regulator of glucocorticoid receptor activity and an Hsp90 cochaperone. FKBP51 has previously been identified as a drug target due to its roles in stress-related disorders and pain tolerance. Two recent publications in Cell Stress and Chaperones further explore FKBP51 functions. To understand whether FKBP51 plays a role in sleep disturbances linked to stress disorders, Gebru et al. examined the role of FKBP51 in regulating the circadian rhythm. Broadening the range of Hsp90 cochaperone function, Jeanne et al. summarized the role of multiple cochaperones in Alzheimer's disease, discussing how cochaperones affect both Aβ and tau. They emphasize the role of FKBP51 in promoting tau pathogenesis and discuss the small molecule LA1011, which binds Hsp90 and competes with Hsp90-FKBP51 interaction. Further studies with LA1011 may lead to new treatments for Alzheimer's disease and will help clarify the contributions of FKBP51 to human disorders.
期刊介绍：
Cell Stress and Chaperones is an integrative journal that bridges the gap between laboratory model systems and natural populations. The journal captures the eclectic spirit of the cellular stress response field in a single, concentrated source of current information. Major emphasis is placed on the effects of climate change on individual species in the natural environment and their capacity to adapt. This emphasis expands our focus on stress biology and medicine by linking climate change effects to research on cellular stress responses of animals, micro-organisms and plants.
