功能： disease:Defects in COLQ are the cause of congenital myasthenic syndrome Engel type (CMSE) [MIM:603034]; also known as end-plate acetylcholinesterase deficiency or congenital myasthenic syndrome type IC (CMS-IC). CMSE is a rare autosomal recessive congenital myastehnic syndrome characterized by onset during childhood, generalized weakness, abnormal fatigability on exertion, refrectoriness to acetylcholinesterase drugs, decremental electromyographic response and morphological abnormalities of the neuromuscular junctions.,domain:The proline-rich attachment domain (PRAD) binds the AChE catalytic subunits.,function:Anchors the catalytic subunits of asymmetric AChE to the synaptic basal lamina.,PTM:The triple-helical tail is stabilized by disulfide bonds at each end.,similarity:Belongs to the COLQ family.,similarity:Contains 2 collagen-like domains.,subunit:Homotrimer. Component of the asymmetric form of AChE, a disulfide-bonded oligomer composed of the collagenic subunits (Q) and a variable number of asymmetric catalytic subunits (T). The N-terminal of a collagenic subunit (Q) associates with the C-terminal of a catalytic subunit (T).,tissue specificity:Found at the end plate of skeletal muscle.,
