LETM1 | POLN |
Mitochondrial proton/calcium antiporter that mediatesproton-dependent calcium efflux from mitochondrion(PubMed:19797662). Crucial for the maintenance of mitochondrialtubular networks and for the assembly of the supercomplexes of therespiratory chain (PubMed:18628306). Required for the maintenanceof the tubular shape and cristae organization (PubMed:18628306).In contrast to SLC8B1/NCLX, does not constitute the major factorfor mitochondrial calcium extrusion (PubMed:24898248).{ECO:0000269|PubMed:18628306, ECO:0000269|PubMed:19797662,ECO:0000269|PubMed:24898248}. | DNA polymerase with very low fidelity that catalyzesconsiderable misincorporation by inserting dTTP opposite a Gtemplate, and dGTP opposite a T template (PubMed:16787914,PubMed:17118716). Is the least accurate of the DNA polymerase Afamily (i.e. POLG, POLN and POLQ) (PubMed:17118716). Can performaccurate translesion DNA synthesis (TLS) past a 5S-thymine glycol.Can perform efficient strand displacement past a nick or a gap andgives rise to an amount of product similar to that on non-damagedtemplate. Has no exonuclease activity (PubMed:16787914). Error-prone DNA polymerase that preferentially misincorporates dTregardless of template sequence (PubMed:25775266). May play a rolein TLS during interstrand cross-link (ICL) repair(PubMed:19908865). May be involved in TLS when genomic replicationis blocked by extremely large major groove DNA lesions. Mayfunction in the bypass of some DNA-protein and DNA-DNA cross-links. May have a role in cellular tolerance to DNA cross-linkingagents (PubMed:20102227). Involved in the repair of DNA cross-links and double-strand break (DSB) resistance. Participates inFANCD2-mediated repair. Forms a complex with HELQ helicase thatparticipates in homologous recombination (HR) repair and isessential for cellular protection against DNA cross-links(PubMed:19995904). {ECO:0000269|PubMed:16787914,ECO:0000269|PubMed:17118716, ECO:0000269|PubMed:19908865,ECO:0000269|PubMed:19995904, ECO:0000269|PubMed:20102227,ECO:0000269|PubMed:25775266}. |
