CC -!- FUNCTION: A calcium channel that regulates synaptic endocytosis and CC hence couples exo- with endocytosis. Isoform A and isoform B are mainly CC required in the nervous system and necessary in photoreceptor cells. CC {ECO:0000269|PubMed:19737521}. CC -!- SUBUNIT: Homomultimer; Isoform B. {ECO:0000269|PubMed:19737521}. CC -!- INTERACTION: CC Q95T12; Q95T12: fwe; NbExp=7; IntAct=EBI-169467, EBI-169467; CC Q95T12-2; Q95T12-2: fwe; NbExp=5; IntAct=EBI-2497181, EBI-2497181; CC -!- SUBCELLULAR LOCATION: Cytoplasmic vesicle, secretory vesicle, synaptic CC vesicle membrane {ECO:0000269|PubMed:19737521}; Multi-pass membrane CC protein {ECO:0000269|PubMed:19737521}. Note=Upon fusion of the synaptic CC vesicle with the presynaptic membrane, protein is present in the CC periactive zones, where endocytosis is known to occur. {ECO:0000255, CC ECO:0000269|PubMed:19737521}. CC -!- ALTERNATIVE PRODUCTS: CC Event=Alternative splicing; Named isoforms=3; CC Name=A {ECO:0000269|PubMed:10731132, ECO:0000269|PubMed:19737521}; CC IsoId=Q95T12-1; Sequence=Displayed; CC Name=B {ECO:0000269|PubMed:10731132, ECO:0000269|PubMed:19737521}; CC IsoId=Q95T12-2; Sequence=VSP_053166; CC Name=C {ECO:0000269|PubMed:10731132, ECO:0000269|PubMed:19737521}; CC IsoId=Q95T12-3; Sequence=VSP_053165; CC -!- TISSUE SPECIFICITY: Isoform B is expressed in the neuropils of CC embryonic, larval, adult CNS, and R1-R6 terminals. Expression in the CC central nervous system (CNS) starts at embryonic stage 13. CC {ECO:0000269|PubMed:19737521}. CC -!- DISRUPTION PHENOTYPE: Impaired intracellular resting calcium levels and CC impaired endocytosis in presynaptic terminals, exocytosis is normal. CC Mutant boutons at the neuromuscular junctions exhibit a significant CC depletion in the number of synaptic vesicles. There are numerous extra CC boutons which are often small, clustered, and flowery in nature. Mutant CC nerve terminals display omega structures and collared pits. CC {ECO:0000269|PubMed:19737521}. CC -!- SIMILARITY: Belongs to the calcium channel flower family. CC {ECO:0000305}.
