Summaries for LYRM4 Gene

Entrez Gene Summary for LYRM4 Gene

  • The protein encoded by this gene is found in both mitochondria and the nucleus, where it binds cysteine desulfurase and helps free inorganic sulfur for Fe/S clusters. Disruption of this gene negatively impacts mitochondrial and cytosolic iron homeostasis. [provided by RefSeq, Sep 2016]

GeneCards Summary for LYRM4 Gene

LYRM4 (LYR Motif Containing 4) is a Protein Coding gene. Diseases associated with LYRM4 include Combined Oxidative Phosphorylation Deficiency 19 and Friedreich Ataxia. Among its related pathways are Metabolism and Mitochondrial iron-sulfur cluster biogenesis.

UniProtKB/Swiss-Prot for LYRM4 Gene

  • Required for nuclear and mitochondrial iron-sulfur protein biosynthesis.

    Quaternary structure:
    • Interacts with FXN. Interaction is increased by nickel. Interaction is inhibited by calcium, magnesium, manganese, copper, cobalt, zinc, and iron. Forms a complex with the cytosolic/nuclear form of NFS1. The complex increased the stability of NFS1.
    • Reduction of LYRM4 levels by siRNA increases the total iron content, and reduces cytosolic and mitochondrial aconitase activities and NFS1 protein levels.
