Summary
TOMM70 (translocase of outer mitochondrial membrane 70, HGNC:11985) is a protein-coding gene on chromosome 3q12.2, encoding Mitochondrial import receptor subunit TOM70 (O94826). Acts as a receptor of the preprotein translocase complex of the outer mitochondrial membrane (TOM complex). It is a selective cancer dependency (DepMap: 24.2% of cell lines).
This gene encodes an import receptor of the outer mitochondrial membrane that is part of the translocase of the outer membrane complex. This protein is involved in the import of mitochondrial precursor proteins. The protein interacts with the SARS-CoV and SARS-Cov-2 ORF9b proteins.

Function. Acts as a receptor of the preprotein translocase complex of the outer mitochondrial membrane (TOM complex). Recognizes and mediates the translocation of mitochondrial preproteins from the cytosol into the mitochondria in a chaperone dependent manner. Mediates TBK1 and IRF3 activation induced by MAVS in response to Sendai virus infection and promotes host antiviral responses during virus infection. Upon Sendai virus infection, recruits HSP90AA1:IRF3:BAX in mitochondrion and the complex induces apoptosis.
Subunit / interactions. Forms part of the preprotein translocase complex of the outer mitochondrial membrane (TOM complex) which consists of at least 7 different proteins (TOMM5, TOMM6, TOMM7, TOMM20, TOMM22, TOMM40 and TOMM70). Interacts with CAPN8. Interacts with TRADD, TRAF6 and STING. Interacts with MAVS; the interaction is enhanced by Sendai virus infection. Interacts with HSPA8 and HSP90AA1; both interactions are required for preprotein mitochondrial import. The interaction with HSP90AA1 is direct and mediates the association of TOMM70 with IRF3 and TBK1. Upon mitochondrial depolarization, interacts with PINK1; the interaction is required for PINK1-TOM-TIM23 supercomplex formation which is critical for PINK1 stabilization at the outer mitochondrial membrane, kinase activation and downstream mitophagy. (Microbial infection) Interacts (via C-terminus) with SARS coronaviru/SARS-CoV and SARS coronavirus-2/SARS-CoV-2 virus protein ORF9b. (Microbial infection) Interacts with parasite T.gondii RH strain MAF1b1; the interaction impairs TOMM70 import activity, enables the parasite to associate with the host mitochondria and facilitates the association of MAF1b1 with MIB complex component SAMM50, promoting the formation of SPOTs (structures positive for outer mitochondrial membrane (OMM)); the interaction is probably indirect.
Subcellular location. Mitochondrion outer membrane.
Similarity. Belongs to the Tom70 family.

Enriched among interaction partners
Reactome pathways and GO biological processes over-represented among this gene’s 104 IntAct physical interaction partners (hypergeometric vs the genome-wide background, BH-FDR, gene-set size 15–500, ranked by fold). A functional readout of the neighbourhood — distinct from this gene’s own memberships above, and biased toward well-studied / hub proteins, so read it as themes rather than proof.
