Functional complementation in yeast established that human ANT2 specifically supports growth under anaerobic conditions, consistent with an ATP-importing rather than ATP-exporting directionality [PMID:16341775], and this ATP-import activity blunts membrane hyperpolarization and limits cell death during hypoxia-reoxygenation [PMID:33255741]. ANT2 expression is tightly controlled at the transcriptional level: Sp1 acts bidirectionally through GC-box elements, with distal A/B boxes activating and a C box adjacent to the start site repressing transcription via positional interaction between Sp1 complexes [PMID:8702555, PMID:11683873], while TGF-β-driven NF1/Smad4 repressor complexes silence ANT2 during replicative, oncogene-induced, drug-induced, and cytokine-induced senescence [PMID:25220407, PMID:25982278]. Loss of ANT2 elevates reactive oxygen species and activates the DNA damage response, linking its downregulation mechanistically to the senescent phenotype [PMID:25220407]. Post-translationally, ANT2 is integrated into a PAK6–SIRT4–ANT2 complex in which PAK6 phosphorylates ANT2 at T107 to inhibit apoptosis while SIRT4 deacetylates K105 to drive ubiquitin-mediated degradation, coordinately controlling ANT2 stability and pro-tumorigenic function [PMID:32194820].

Ant2 is also required cell-autonomously for erythroid and B-lymphocyte maturation [PMID:25613378].

In addition to its ADP:ATP antiporter activity, also involved in mitochondrial uncoupling and mitochondrial permeability transition pore (mPTP) activity (By similarity). Plays a role in mitochondrial uncoupling by acting as a proton transporter: proton transport uncouples the proton flows via the electron transport chain and ATP synthase to reduce the efficiency of ATP production and cause mitochondrial thermogenesis (By similarity). Proton transporter activity is inhibited by ADP:ATP antiporter activity, suggesting that SLC25A5/ANT2 acts as a master regulator of mitochondrial energy output by maintaining a delicate balance between ATP production (ADP:ATP antiporter activity) and thermogenesis (proton transporter activity) (By similarity). Proton transporter activity requires free fatty acids as cofactor, but does not transport it (By similarity). Probably mediates mitochondrial uncoupling in tissues that do not express UCP1 (By similarity). Also plays a key role in mPTP opening, a non-specific pore that enables free passage of the mitochondrial membranes to solutes of up to 1.5 kDa, and which contributes to cell death (PubMed:31883789). It is however unclear if SLC25A5/ANT2 constitutes a pore-forming component of mPTP or regulates it (By similarity). Acts as a regulator of mitophagy independently of ADP:ATP antiporter activity: promotes mitophagy via interaction with TIMM44, leading to inhibit the presequence translocase TIMM23, thereby promoting stabilization of PINK1 (By similarity). As part of the mitotic spindle-associated MMXD complex it may play a role in chromosome segregation (PubMed:20797633)","subcellular_location":"Mitochondrion inner membrane; Membrane","url":"https://www.uniprot.org/uniprotkb/P05141/entry"},"depmap":{"release":"DepMap","has_data":true,"is_common_essential":true,"resolved_as":"","url":"https://depmap.org/portal/gene/SLC25A5","classification":"Common Essential","n_dependent_lines":366,"n_total_lines":1208,"dependency_fraction":0.3029801324503311},"opencell":{"profiled":false,"resolved_as":"","ensg_id":"","cell_line_id":"","localizations":[],"interactors":[{"gene":"CAPZB","stoichiometry":0.2},{"gene":"RTN4","stoichiometry":0.2}],"url":"https://opencell.sf.czbiohub.org/search/SLC25A5","total_profiled":1310},"omim":[{"mim_id":"619667","title":"SOLUTE CARRIER FAMILY 35, MEMBER F6; SLC35F6","url":"https://www.omim.org/entry/619667"},{"mim_id":"618566","title":"ADENINE NUCLEOTIDE TRANSLOCASE LYSINE METHYLTRANSFERASE; ANTKMT","url":"https://www.omim.org/entry/618566"},{"mim_id":"616310","title":"RHO GTPase-ACTIVATING PROTEIN 11B; ARHGAP11B","url":"https://www.omim.org/entry/616310"},{"mim_id":"614778","title":"CYTOSOLIC IRON-SULFUR ASSEMBLY COMPONENT 2B; CIAO2B","url":"https://www.omim.org/entry/614778"},{"mim_id":"614777","title":"MMS19 HOMOLOG, CYTOSOLIC IRON-SULFUR ASSEMBLY COMPONENT; MMS19","url":"https://www.omim.org/entry/614777"}],"hpa":{"profiled":true,"resolved_as":"","reliability":"Supported","locations":[{"location":"Mitochondria","reliability":"Supported"}],"tissue_specificity":"Low tissue specificity","tissue_distribution":"Detected in all","driving_tissues":[],"url":"https://www.proteinatlas.org/search/SLC25A5"},"hgnc":{"alias_symbol":["T2","2F1","T3"],"prev_symbol":["ANT2"]},"alphafold":{"accession":"P05141","domains":[{"cath_id":"1.50.40.10","chopping":"4-297","consensus_level":"medium","plddt":91.6376,"start":4,"end":297}],"viewer_url":"https://alphafold.ebi.ac.uk/entry/P05141","model_url":"https://alphafold.ebi.ac.uk/files/AF-P05141-F1-model_v6.cif","pae_url":"https://alphafold.ebi.ac.uk/files/AF-P05141-F1-predicted_aligned_error_v6.png","plddt_mean":91.75},"mouse_models":{"mgi_url":"https://www.informatics.jax.org/marker/summary?nomen=SLC25A5","jax_strain_url":"https://www.jax.org/strain/search?query=SLC25A5"},"sequence":{"accession":"P05141","fasta_url":"https://rest.uniprot.org/uniprotkb/P05141.fasta","uniprot_url":"https://www.uniprot.org/uniprotkb/P05141/entry","alphafold_viewer_url":"https://alphafold.ebi.ac.uk/entry/P05141"}},"corpus_meta":[{"pmid":"1242390","id":"PMC_1242390","title":"Opposite effects of dexamethasone on serum concentrations of 3,3',5'-triiodothyronine (reverse T3) and 3,3'5-triiodothyronine (T3).","date":"1975","source":"The Journal of clinical endocrinology and metabolism","url":"https://pubmed.ncbi.nlm.nih.gov/1242390","citation_count":343,"is_preprint":false},{"pmid":"3308116","id":"PMC_3308116","title":"Yeast mitochondrial RNA polymerase is homologous to those encoded by bacteriophages T3 and T7.","date":"1987","source":"Cell","url":"https://pubmed.ncbi.nlm.nih.gov/3308116","citation_count":341,"is_preprint":false},{"pmid":"9295285","id":"PMC_9295285","title":"Substrate specificities of three members of the human UDP-N-acetyl-alpha-D-galactosamine:Polypeptide N-acetylgalactosaminyltransferase family, GalNAc-T1, -T2, and -T3.","date":"1997","source":"The Journal of biological chemistry","url":"https://pubmed.ncbi.nlm.nih.gov/9295285","citation_count":253,"is_preprint":false},{"pmid":"8813722","id":"PMC_8813722","title":"Identification of TRACs (T3 receptor-associating cofactors), a family of cofactors that associate with, and modulate the activity of, nuclear hormone receptors.","date":"1996","source":"Molecular endocrinology (Baltimore, Md.)","url":"https://pubmed.ncbi.nlm.nih.gov/8813722","citation_count":210,"is_preprint":false},{"pmid":"3104527","id":"PMC_3104527","title":"Endocytosis and recycling of the T3-T cell receptor complex.
