What's a GeneRIF?

Through bioinformatics prediction, we found miR-33a directly targeted on the 3'-UTR of NDUFA5. Dual-luciferase reporter analysis further confirmed the direct suppression of miR-33a on NDUFA5 expression
Title: Hepatocyte miR-33a mediates mitochondrial dysfunction and hepatosteatosis by suppressing NDUFA5.
At the age of 11 months, mice with a central nervous system knockout of Ndufa5 (Ndufa5 CNS-KO) showed lethargy and loss of motor skills. In these mice cortices, the levels of NDUFA5 protein were reduced to 25% of controls. Fully assembled complex I (CI) levels were also greatly reduced in cortex and CI activity in homogenates was reduced to 60% of controls.
Title: Partial complex I deficiency due to the CNS conditional ablation of Ndufa5 results in a mild chronic encephalopathy but no increase in oxidative damage.
The real-time RT-PCR analysis revealed that the expressions of the NDUFA5 mRNA, but not the ZNF9 mRNA level, were significantly up-regulated in all the tested cell lines derived from HPV-positive cervical cancer, HeLa, SW576, and CaSKi.
Title: Identification of NADH dehydrogenase 1 alpha subcomplex 5 capable to transform murine fibroblasts and overexpressed in human cervical carcinoma cell lines.

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.
