A total of 618,412 particles were used for the consensus reconstruction with an overall resolution of 4.06 Angstrom (FSC 0.143 cut off). Focused 3D classification and local refinement were performed in several regions of the complex. A composite map was generated using focused reconstructions of ZCCHC8 HD/KID-MTR4 KOW (3.26 Angstrom, FSC = 0.143; 117,561 particles), protomer A MTR4 (3.42 Angstrom, FSC = 0.143; 225,213 particles), protomer B MTR4 (3.54 Angstrom, FSC = 0.143; 236,602 particles), protomer A MTR4 core-ZCCHC8 PSP-RBM7 RRM (4.06 Angstrom, FSC = 0.143; 44,800 particles), and protomer B MTR4 core-ZCCHC8 PSP-RBM7 RRM (4.4 Angstrom, FSC = 0.143 37,088 particles).
