General annotation (Comments)
| Function | Anchors the catalytic subunits of asymmetric AChE to the synaptic basal lamina. |
| Subunit structure | 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). |
| Subcellular location | |
| Tissue specificity | Found at the end plate of skeletal muscle. |
| Domain | The proline-rich attachment domain (PRAD) binds the AChE catalytic subunits. |
| Post-translational modification | The triple-helical tail is stabilized by disulfide bonds at each end. |
| Involvement in disease | Myasthenic syndrome, congenital, Engel type (CMSE) [MIM:603034]: A rare autosomal recessive congenital myasthenic 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. |
| Sequence similarities | Belongs to the COLQ family. Contains 2 collagen-like domains. |

| This entry describes 8 isoforms produced by alternative splicing. [Align] [Select] | ||||||
| Isoform I (identifier: Q9Y215-1) This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry. | ||||||
| Isoform II (identifier: Q9Y215-2) The sequence of this isoform differs from the canonical sequence as follows: 1-35: MVVLNPMTLGIYLQLFFLSIVSQPTFINSVLPISA → MTGSSFSLAHLLIISGLLCYSAGCL | ||||||
| Isoform III (identifier: Q9Y215-3) The sequence of this isoform differs from the canonical sequence as follows: 74-107: Missing. | ||||||
| Isoform IV (identifier: Q9Y215-4) The sequence of this isoform differs from the canonical sequence as follows: 73-76: Missing. | ||||||
| Isoform V (identifier: Q9Y215-5) The sequence of this isoform differs from the canonical sequence as follows: 124-132: Missing. | ||||||
| Isoform VI (identifier: Q9Y215-6) The sequence of this isoform differs from the canonical sequence as follows: 240-291: GQKGDSGVMG...RGFPGPPGRC → SSRTPCTLPR...DYISSGTERG 292-455: Missing. | ||||||
| Isoform VII (identifier: Q9Y215-7) The sequence of this isoform differs from the canonical sequence as follows: 272-281: GQLIMGPKGE → DFCGQQPGGA 282-455: Missing. | ||||||
| Note: May be produced at very low levels due to a premature stop codon in the mRNA, leading to nonsense-mediated mRNA decay. | ||||||
| Isoform VIII (identifier: Q9Y215-8) The sequence of this isoform differs from the canonical sequence as follows: 273-329: QLIMGPKGER...FVVNNQEELE → HMETCNAPST...VLAPSPPTFV 330-455: Missing. |
