Background Information
QKI (Quaking) is RNA-binding protein that plays a central role in myelinization (PMID: 16641098). It regulates pre-mRNA splicing, mRNA export and protein translation (PMID: 16641098). It acts upstream of or within several processes, including long-chain fatty acid biosynthetic process, positive regulation of macromolecule metabolic process and vasculogenesis. QKI shuttles internal m7G-modified transcripts into stress granules and modulates mRNA metabolism. It is expressed in the frontal cortex of brain (PMID: 16342280).
