In #cancer, Casein Kinase 2 (CK2) interacts with #HSP90 and puts phosphate groups on Serine 255 and Serine 226 positions of the charged linker region of HSP90 thereby changing its structure or conformation. This dangerous alter ego of HSP90 helps the cancer cells to survive. (7)

This switch of HSP90 to "bad" and the formation of the epichaperome makes it so the #epichaperome now aids #cancer. (6)

#Cancer is a multifactorial disease that manifests as a result of chronic cellular stress, a trigger that turns #HSP90 into Mr. Hyde.
Mr. Hyde can now associate with other chaperone protein members and form a gang (high molecular weight assembly) called “epichaperome”. (5)

In our latest work, now published in
@natcomms.nature.com, we uncover how #HSP90 switches from “good” to “bad” in #cancer. (4)

Heat Shock Protein 90 (HSP90) is a cellular chaperone protein ubiquitously present in human body and is responsible for folding other important proteins in the cell. However, it can exist either as Dr. Jekyll or Mr. Hyde depending on how stressed the cells are. (3) #cellstress #HSP90

Any protein consists of strings of amino acids that fold into distinct different shapes and structures inside the cell depending on the cellular environment. (2)

🔗 Protein connectivity changes detected by dfPPI show minimal correlation with overall protein expression—demonstrating the need to look beyond protein levels to understand true disease biology. #Proteomics #dfPPI
