Report Abuse. Transcription does require a helicase. In eukaryotes, TFiiH (one of the general transcription factors of the transcription pre-initiation complex) has helicase activity and aids in the formation of the transcription bubble. Erin Â· 2 years ago.
Besides their function in DNA replication and repair, another function of annealing helicases might be in DNA transcription (Figure 3(c)). Cas3 is a superfamily 2 helicase that possesses ATPase, helicase, and nuclease activities as evident in the Cas3 protein of Streptococcus thermophilus [ 133 ].ompared with RNA helicase, more DNA helicases have been found to possess annealing activity (Table 1). The Janscak lab is the first to report that both unwinding and annealing activity resided in a DNA helicase, RECQ5 Î² in 2004 [ 55 ]. RECQ5 Î² is the longer isoform of RECQ5 helicase and is localized in the nucleus.
