General annotation (Comments)

Function

Postsynaptic protein required for clustering of nicotinic acetylcholine receptors (nAChRs) at the neuromuscular junction. It may link the receptor to the underlying postsynaptic cytoskeleton, possibly by direct association with actin or spectrin By similarity.

Subcellular location

Cell membrane; Peripheral membrane protein; Cytoplasmic side. Cell junctionsynapsepostsynaptic cell membrane; Peripheral membrane protein; Cytoplasmic side. Cytoplasmcytoskeleton. Note: Cytoplasmic surface of postsynaptic membranes.

Tissue specificity

Expressed in muscle fibers and in neurons.

Domain

A cysteine-rich region homologous to part of the regulatory domain of protein kinase C may be important in interactions of this protein with the lipid bilayer.

Sequence similarities

Belongs to the RAPsyn family.

Contains 1 RING-type zinc finger.

Contains 7 TPR repeats.
