Acetylcholinesterase collagenic tail peptide also known as AChE Q subunit, acetylcholinesterase-associated collagen, or ColQ is the collagen-tail subunit of acetylcholinesterase found in the neuromuscular junction. In humans it is encoded by the COLQ gene.[5][6]
Function
This gene encodes the subunit of a
isoforms have been found for this gene.[6]
Clinical significance
Mutations in this gene are associated with endplate acetylcholinesterase deficiency.[6]
