Mtln overexpression increases mitochondrial membrane potential, respiration rates, and Ca(2+) retention capacity while decreasing mitochondrial ROS and matrix-free Ca(2+). Mtln-knockout mice display perturbations in mitochondrial respiratory (super)complex formation and activity, fatty acid oxidation, tricarboxylic acid (TCA) cycle enzymes, and Ca(2+) retention capacity.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

Suppressed Reference Sequence(s)

The following Reference Sequences have been suppressed. Explain

NM_175125.2: Suppressed sequence

Description

NM_175125.2: This RefSeq was permanently suppressed because it is a nonsense-mediated mRNA decay (NMD) candidate, and because there is no support for the predicted protein.
