CC -!- FUNCTION: Component of the MICOS complex, a large protein complex of
CC the mitochondrial inner membrane that plays crucial roles in the
CC maintenance of crista junctions, inner membrane architecture, and
CC formation of contact sites to the outer membrane.
CC {ECO:0000269|PubMed:21944719, ECO:0000269|PubMed:21987634}.
CC -!- SUBUNIT: Component of the mitochondrial contact site and cristae

CC junctions. {ECO:0000269|PubMed:21944719, ECO:0000269|PubMed:21987634,
CC ECO:0000269|PubMed:22009199}.
CC -!- DISRUPTION PHENOTYPE: Moderate changes in the mitochondrial morphology.
CC {ECO:0000269|PubMed:21987634}.
CC -!- MISCELLANEOUS: Present with 5220 molecules/cell in log phase SD medium.
CC {ECO:0000269|PubMed:14562106}.
CC -!- SIMILARITY: Belongs to the apolipoprotein O/MICOS complex subunit Mic27
CC family. Yeast Mic26 subfamily. {ECO:0000305}.
