NCIt definition : Acetylcholinesterase collagenic tail peptide (455 aa, 48 kDa) is encoded by the human
COLQ gene. This protein plays a role in localizing asymmetric acetylcholinesterase
to the endplate of the neuromuscular junction.;
NCIt note : Acetylcholinesterase collagenic tail peptide is a collagen-like protein that forms
a triple helix in the synaptic basal lamina of the endplate of the neuromuscular junction;
each helix contains a proline-rich attachment domain (PRAD), which associates with
acetylcholinesterase tetramers to anchor the catalytic subunits to the endplate.;
