Cell Biol. 8:1143-1148(2006). CC -!- FUNCTION: Exhibits calcium-dependent phospholipid binding properties CC (By similarity). May function in membrane trafficking. Regulates CC synaptic levels of nicotinic acetylcholine receptor subunit lev-1 and CC unc-38 in the nerve cord (PubMed:15990870). Involved in nicotinic CC acetylcholine receptor (nAChR)-mediated sensitivity to nicotine and CC levamisole (PubMed:15990870). Affects directional sperm motility CC (PubMed:16998478). {ECO:0000250|UniProtKB:Q99829, CC ECO:0000269|PubMed:15990870, ECO:0000269|PubMed:16998478}. CC -!- COFACTOR: CC Name=Ca(2+); Xref=ChEBI:CHEBI:29108; CC Evidence={ECO:0000255|PROSITE-ProRule:PRU00041}; CC -!- SUBUNIT: Interacts with nicotinic acetylcholine receptor. CC {ECO:0000269|PubMed:16998478}. CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000269|PubMed:15990870}; CC Peripheral membrane protein {ECO:0000269|PubMed:15990870}. CC -!- ALTERNATIVE PRODUCTS: CC Event=Alternative splicing; Named isoforms=2; CC Name=a; CC IsoId=Q9XUB9-1; Sequence=Displayed; CC Name=b; CC IsoId=Q9XUB9-2; Sequence=VSP_039297; CC -!- TISSUE SPECIFICITY: Expressed in head and tail neurons, ventral cord CC moto-neurons, body wall muscles and hypodermal cells of the vulva. CC {ECO:0000269|PubMed:15990870}. CC -!- DOMAIN: C2 domains are necessary for calcium-dependent cell membrane CC association. C2 domains are necessary for neuronal progenitor cell CC differentiation in a calcium-independent manner. CC {ECO:0000250|UniProtKB:Q99829}. CC -!- DISRUPTION PHENOTYPE: Sperm directional motility defects CC (PubMed:16998478). RNAi-mediated knockdown causes a moderate resistance CC to nicotine-induced paralysis and a decrease in unc-38 synaptic CC expression along nerve cords without affecting lev-1 cellular CC expression levels in muscles (PubMed:15990870). CC {ECO:0000269|PubMed:15990870, ECO:0000269|PubMed:16998478}. CC -!- SIMILARITY: Belongs to the copine family. {ECO:0000305}.
