The overarching goal of delineating molecular principles underlying differentiation of protein kinase clients and chaperone-based modulation of kinase activity is fundamental to understanding activity of many oncogenic kinases that require chaperoning of Hsp70 and Hsp90 systems to attain a functionally competent active form. Despite structural similarities and common activation mechanisms shared by cyclin-dependent kinase (CDK) proteins, members of this family can exhibit vastly different chaperone preferences. The molecular determinants underlying chaperone dependencies of protein kinases are not fully understood as structurally similar kinases may often elicit distinct regulatory responses to the chaperone. The regulatory divergences observed for members of CDK …

Proteins and their unique structures are important due to their involvement in every cellular task, but the protein can only function properly when it is in the correct fold. β-sheet peptides and collagen were observed via structural studies. Circular dichroism (CD) determines a protein’s secondary structure. WKWK, a beta-sheet peptide, is known to dissolve in aqueous solutions. However, WKWK was observed to precipitate out of deionized water. To investigate the cause of this precipitation, Inductively Coupled Plasma Mass Spectroscopy (ICP-MS) was used to determine the ion content of the water. Elevated sodium ion concentrations were found to disrupt the stabilizing …
