Figure Lengend Snippet: Fig. 1 | Association of MTBP and phospho-RecQL4 with pre-RCs at baseline and dormant replication origins. A Baseline and dormant origins. Top, experimental procedure. SIRT1 deficient (SIRT1Null) HCT116 cells were complemented with either WT-SIRT1 (WTSIRT1) or H363Y-SIRT1 (an inactive mutant; MutSIRT1) cDNA15. Replication origins were mapped using nascent strand sequencing (NS-seq)15. Bottom, a gen- ome browser view of NS-seq coverage across a representative genomic region on chromosome 1. Baseline origins (black rectangles) are defined as active in both WTSIRT1 and MutSIRT1 cells, whereas dormant origins (dashed black rectangles) are active only in MutSIRT1 cells. Pre-RNase treatment serves as a control, as RNA primer removal allows lambda exonuclease to digest nascent DNA, eliminating origin peaks. B Nascent strand abundance (initiation) at baseline and dormant origins in cells harboring WTSIRT1 (WT) or MutSIRT1 (Mut). C HCT116 cells containing auxin – inducible degron MCM2 (MCM2-mAID) were complemented with either intact (WT) or S139A substituted MCM215. IAA (auxin, 500 μM for 16 h) depleted the endogenous MCM2-mAID. Complementation with MCM2-S139A, but not WT MCM2, inhibited replication initiation15 (Supplementary Fig. 1E).
