Mass spectrometry and phosphorylation analysis of ORC1 protein, wild type or RNA-binding mutant (R441A, R444A and R465A), in GAA-RNA (RNA interactors of ORC1 identified by RIP-seq and iCLIP) knockdown or control conditions.


ABSTRACT: Mass spectrometry of wild type or mutant (RNA-binding) ORC1. Experiments were done in cellstransfected with a control ASO or an anti-GAA ASO, to knockdown RNA interactors of ORC1.

Cells must coordinate the activation of thousands of replication origins dispersed throughout their genome. Active transcription is known to favor the formation of mammalian origins, although the role that RNA plays in this process remains unclear. We show that the ORC1 subunit of the human Origin Recognition Complex interacts with RNAs transcribed from genes with origins in their transcription start sites (TSSs), displaying a positive correlation between RNA binding and origin activity.
