WebJun 16, 2024 · Genetic encoding of a photocaged serine in the TET1 active site enables its translation in an inactive state, followed by its light activation and monitoring of global 5hmC formation in a virtually 5hmC-free genomic background. Coexpression of TET1 with the five human core family MBDs leads to differential modulation of oxidation with MBD1 ... WebOct 7, 2016 · For example, the catalytic domain of the human tyrosine kinase Src has 8 cysteine residues and 12 serine residues , and we randomly selected three sites for insertion of the photocaged intein . We sandwiched the intein between Gly276 and Cys277, or Val399 and Cys400 of Src (F1 and F2 in Fig. 1a ).

In another example, Chen et al. synthesized two-photon-activatable chemokine CCL5 using photocaged serine through efficient one-pot total chemical synthesis. The chemical groups at serine residues successfully caged the hCCL5 activity, which allowed a spatiotemporally controlled photoactivation of the chemokine activity [22]. WebMethyl-CpG binding domain (MBD) proteins and ten-eleven-translocation (TET) dioxygenases are the readers and erasers of 5-methylcytosine (5mC), the central epigenetic mark of mammalian DNA. We employ light-activatable human TET1 controlled by a genetically encoded photocaged serine to enable in vivo … WebWe have recently reported the direct light activation of TET dioxygenases in cells by the incorporation of 4,5-dimethoxy-2-nitrobenzyl-L-serine (1, Figure 3 a) via amber suppression. 18 We ... nalanda near city
