Comparison of solved and predicted structures of the human NALCN-FAM155 dimer. (A) Structural alignment of the solved structure of human NALCN and FAM155A (from PDB accession number 7SX4) and AlphaFold3-predicted structures of these proteins in complex with each other. (B) Close-up view of the region corresponding to the red dashed box in panel A. A version of these predicted structures, colored according to pLDDT confidence scores, is provided in Fig. S6 A.
