Interaction interfaces of the MICU1–MICU2 heterodimer and comparison with MICU homodimers. Cartoon representations of interfaces 1 and 2 in the MICU1–MICU2 heterodimer (Mol AB and CD) and homodimers in MICU1 or MICU2. (a), (b) The side chains of residues participating in interface 1 interactions of (a) Mol AB, CD, and (b) the homodimers in MICU1 and MICU2 are shown in the stick form. (c), (d) The side chains of residues participating in interface 2 interactions of (c) Mol AB, CD, and (d) homodimers in MICU1 and MICU2 are shown in the stick form. The white dashed lines and red dotted circles denote electrostatic interactions and salt bridges, respectively.
