KhpA forms a complex with RNA binding protein KhpB in cells. Silver-stained SDS-PAGE gel from co-IP experiments, performed using KhpA-L-FLAG3 (IU9602, lane 1), WT (IU1945, lane 2 non-flagged control), or KhpB-L-FLAG3 (IU10664, lane 3) as bait (see Experimental procedures). Prey bands from lanes 1 and 3 were identified by MS as KhpB and KhpA, respectively. The experiment was performed independently twice. Indicated calculated molecular masses of bands are consistent with a standard ladder that is not shown.
