Proteins destined for the secretory compartment of the cell are cotranslationally translocated into the endoplasmic reticulum. The majority of these proteins are N-glycosylated, a co- and posttranslational modification that ensures proper protein folding, stability, solubility, and cellular localization. Here, we show that the subunit of the signal recognition particle receptor (SR) is required for assembly of the N-glycosylation–competent translocon. We report that guanine analog chemical probes identified by high-throughput screening or mutation of the SR- guanosine triphosphate binding site cause an N-glycosylation–deficient phenotype. Neither method alters the association of SR- with SR-, but both approaches reduce the association of SR- with the oligosaccharyltransferase complex. These experiments demonstrate that SR- has a previously unrecognized function coordinating endoplasmic reticulum translation with N-glycosylation. Handover of the RNC complex to an N-glycosylation competent translocon is dependent on SR- facilitated recruitment of the OST.
