Web1 day ago · They designed their peptide with a sequence identical to that of a segment of CDK5 known as the T loop, which is a structure critical to the binding of CDK5 to P25. The entire peptide is only 12 amino acids long — slightly longer than most existing peptide drugs, which are five to 10 amino acids long. WebCyclins activate CDKs by inducing a conformation change in CDKs that open an ATP-binding pocket. Peptide sequences in CDK substrates can then gain access to the pocket and be phosphorylated. CDK activity is also regulated by phosphorylation. CDK-activating kinases phoshporylate CDKs and increase the kinase activity. In contrast, Wee1 ... chemists formby
