WebPoly (ADP-ribose) polymerase I (PARP1) regulates alternative splicing through both its presence on chromatin as well as its PARylation activity. However, no studies have investigated PARP1’s possible role in regulating circRNA biogenesis. Here, we hypothesized that PARP1’s role in splicing extends to circRNA biogenesis. WebThe promoter is the binding site for RNA polymerase. It usually lies 5’ to, or upstream of the transcription start site. Binding of the RNA polymerase positions the enzyme to near the transcription start site, where it will …
