the role of miR-126 and TOMM40 in heat stressed cardiomyocytes, is reported.
Title: Epigenetic upregulation of miR-126 induced by heat stress contributes to apoptosis of rat cardiomyocytes by promoting Tomm40 transcription.
interaction between Tom40 and presequence peptides is mainly electrostatic in nature
Title: Structural characterisation of a full-length mitochondrial outer membrane TOM40 preprotein translocase: implications for its interaction with presequence peptides.
Import of Tom40 did not differ between young and aged animals, but its subsequent assembly into the final approximately 380 kDa complex was higher in mitochondria from aged compared with young animals. Chornic contractile activity altered Tom40 levels.
Title: Biogenesis of the mitochondrial Tom40 channel in skeletal muscle from aged animals and its adaptability to chronic contractile activity.
Tom40B is a functional component of mitochondrial outer membrane translocase
Title: Identification and characterization of a new tom40 isoform, a central component of mitochondrial outer membrane translocase.
C-terminal half of rTOM40 constitutes the preprotein recognition domain with an enriched beta-structure
Title: Membrane-embedded C-terminal segment of rat mitochondrial TOM40 constitutes protein-conducting pore with enriched beta-structure.

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.
