Protein attributes

Sequence length	457 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at transcript level

General annotation (Comments)

Function	Anchors the catalytic subunits of asymmetric AChE to the synaptic basal lamina By similarity.
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) By similarity.
Subcellular location	Cell junction › synapse By similarity.
Domain	The proline-rich attachment domain (PRAD) binds the AChE catalytic subunits By similarity.
Post-translational modification	The triple-helical tail is stabilized by disulfide bonds at each end By similarity.
Sequence similarities	Belongs to the COLQ family. Contains 2 collagen-like domains.
