WebJul 19, 2024 · CTC1 and STN1 are sufficient to terminate telomerase action. Given that CST inhibits telomerase activity 13, the above results imply that key phenotypic differences in the effect of CTC1 versus TEN1 disruption (i.e., excessive G- overhang elongation, damage signaling and growth arrest in CTC −/− cells) reflect a requirement for CTC1 but … WebCST was solved by cryo-EM, allowing the design of mutant proteins defective in telomeric ssDNA bind-ing and prompting the reexamination of CST inhibi-tion of telomerase. The previous proposal that hu-man CST inhibits telomerase by sequestration of the DNA primer was tested with a series of DNA-binding mutants of CST and modeled by a …
CST does not evict elongating telomerase but prevents
WebAbstract. The CST complex (CTC1-STN1-TEN1) has been shown to inhibit telomerase extension of the G-strand of telomeres and facilitate the switch to C-strand synthesis by DNA polym WebThe previous proposal that human CST inhibits telomerase by sequestration of the DNA primer was tested with a series of DNA-binding mutants of CST and modeled by a competitive binding simulation. The DNA-binding mutants had substantially reduced ability to inhibit telomerase, as predicted from their reduced affinity for telomeric DNA. did the mets play a doubleheader today
