Also known as: CMS10; CMS1B; FADS3; C4orf25
Summary: The protein encoded by this gene is essential for neuromuscular synaptogenesis. The protein functions in aneural activation of muscle-specific receptor kinase, which is required for postsynaptic differentiation, and in the subsequent clustering of the acetylcholine receptor in myotubes. This protein can also induce autophosphorylation of muscle-specific receptor kinase. Mutations in this gene are a cause of familial limb-girdle myasthenia autosomal recessive, which is also known as congenital myasthenic syndrome type 1B. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Sep 2009]

Data showed that DOK7 transcript variants 1 (DOK7V1) were decreased in lung cancer, and associated with poor overall survival and progressionfree survival. Its overexpression limited the proliferation and migration, but enhanced the adhesion to the extracellular matrix, of lung cancer cells. Further data indicate that DOK7V1 may inhibit proliferation and migration via negatively regulating the PI3K/AKT/mTOR signaling.

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.
