MTCH2/MIMP is a surface-exposed outer mitochondrial membrane protein that acts as a receptor facilitating recruitment of tBID to mitochondria; knockout in embryonic stem cells, mouse embryonic fibroblasts, and conditional knockout in liver hinders tBID recruitment, Bax/Bak activation, MOMP, and apoptosis, establishing MTCH2 as a critical facilitator of the death-receptor apoptotic pathway |

MTCH2 is a negative regulator of mitochondrial oxidative phosphorylation (OXPHOS) downstream of BID; loss of MTCH2 in haematopoietic stem cells increases mitochondrial OXPHOS, mitochondrial size, ATP and ROS levels, and triggers HSC and progenitor entry into cell cycle, demonstrating MTCH2's indispensable role in maintaining HSC homeostasis |

MTCH2 is a regulator of mitochondrial fusion essential for naïve-to-primed pluripotency interconversion in murine ESCs; MTCH2-/- ESCs fail to elongate mitochondria and fail to exit naïve pluripotency, and enforced mitochondrial elongation via MFN2 overexpression or dominant-negative DRP1 rescues this defect |

MTCH2 is a mitochondrial outer membrane protein insertase required for insertion of biophysically diverse tail-anchored (TA), signal-anchored, and multipass α-helical proteins but not β-barrel proteins; purified MTCH2 is sufficient to mediate insertion into reconstituted proteoliposomes; membrane-embedded hydrophilic residues are functionally critical; MTCH2 acts as a gatekeeper preventing mislocalization of TAs to the ER and modulates leukemia cell apoptosis sensitivity; MTCH2 appears to have evolved from a solute carrier transporter |

MTCH2 cooperates with the ubiquitin E3 ligase MARCH5 and E2 conjugating enzyme UBE2K to mark MCL1 for proteasomal degradation specifically when MCL1 is engaged by NOXA; this requires the MCL1 transmembrane domain and specific MCL1 lysine residues, suggesting the complex acts on MCL1:NOXA within the mitochondrial outer membrane |

Stop codon read-through of MTCH2 mRNA generates two additional isoforms (MTCH2x and MTCH2xx); MTCH2 and MTCH2x localize to mitochondria with long half-life (>36 h), but MTCH2xx mislocalizes to the cytoplasm with rapid degradation (t1/2 <1 h); MTCH2 read-through-deficient cells generated by CRISPR-Cas9 show increased MTCH2 expression and decreased mitochondrial membrane potential, indicating that double-SCR regulates MTCH2 expression levels and mitochondrial membrane potential |
