PF3D7_1203000 origin recognition complex subunit 1

Colocalization of PfPCNA1 and PfORC1 during the replicating-trophozoite stage. A glass slide containing a parasite smear from the replicating-trophozoite stage or schizont stage was treated for immunofluoresence studies as described in Materials and Methods using both anti-PfORC1 and anti-PfPCNA1 antibodies. Distinct colocalization of PfORC1 and PfPCNA1 foci can be detected during the replicating-trophozoite stage (Troph.; rows 1 to 3). Although the expression of PfPCNA can be detected at the multinucleated late schizont stage (rows 4 and 5), the expression of PfORC1 is barely visible as the protein is degraded at the late stage, as described earlier. DAPI (4’,6-diamidino-2-phenylindole) (I) shows the nuclei. Column IV represents merged panels I, II, and III.
