WebMar 6, 2024 · The controlled release of promoter-proximal paused RNA polymerase II (Pol II) into productive elongation is a major step in gene regulation. However, functional analysis of Pol II pausing is difficult because factors that regulate pause release are almost all essential. In this study, we identified heterozygous loss-of-function mutations in SUPT5H , … Webcoding strand. Transcription over GC skew results in the formation of RNA-DNA hybrid structures (R-loops), which can cause DNA damage if left unresolved. We hypothesize that distal pausing plays a role in the formation of CGI R-loops, and that the resolution of such structures is necessary for the release of the distal pause and proper gene ...
