Summary Acetylcholine receptors at mature mammalian neuromuscular junctions are pentameric protein complexes composed of four subunits in the ratio of two alpha subunits to one beta, one epsilon, and one delta subunit. The acetylcholine receptor changes subunit composition shortly after birth when the epsilon subunit replaces the gamma subunit seen in embryonic receptors. Mutations in the epsilon subunit are associated with congenital myasthenic syndrome. [provided by RefSeq, Sep 2009].

What is the normal function of the CHRNE gene?

The CHRNE gene provides instructions for making the epsilon (ε) component (subunit) of the acetylcholine receptor (AChR) protein. The AChR protein is found in the membrane of skeletal muscle cells and plays a critical role in the neuromuscular junction, which is the area where signaling between nerve and muscle cells occurs. Signaling between nerve and muscle cells is necessary for movement. The AChR protein consists of five subunits, each of which is produced from a different gene. The subunits are assembled into the AChR protein in the endoplasmic reticulum, a cell structure involved in protein processing and transport, before being transported to the cell membrane. There are two major forms of the AChR protein, a fetal type that is present before birth and an adult type. The ε subunit is found only in the adult AChR protein. At about the 33rd week of pregnancy, the ε subunit replaces the gamma (γ) subunit (found only in fetal AChR) to form adult AChR protein.
