CC -!- FUNCTION: Complexin that regulates SNARE protein complex-mediated CC synaptic vesicle fusion (By similarity). Required for the maintenance CC of synaptic ultrastructure in the adult retina (By similarity). CC Positively regulates synaptic transmission through synaptic vesicle CC availability and exocytosis of neurotransmitters at photoreceptor CC ribbon synapses in the retina (By similarity). Suppresses tonic CC photoreceptor activity and baseline 'noise' by suppression of Ca(2+) CC vesicle tonic release and the facilitation of evoked synchronous and CC asynchronous Ca(2+) vesicle release (By similarity). CC {ECO:0000250|UniProtKB:Q8R1B5}. CC -!- SUBUNIT: Binds to the SNARE core complex containing SNAP25, VAMP2 and CC STX1A. {ECO:0000250|UniProtKB:Q8R1B5}. CC -!- SUBCELLULAR LOCATION: Cell junction, synapse CC {ECO:0000250|UniProtKB:Q8R1B5}. Cell membrane; Lipid-anchor CC {ECO:0000250|UniProtKB:Q8R1B5}. Note=Enriched at the synaptic terminal CC (By similarity). Localized at glycinergic synaptic contacts of AII CC amacrine cells with OFF cone bipolar cells in the OFF sublamina of the CC retina inner nuclear layer (By similarity). CC {ECO:0000250|UniProtKB:Q8R1B5}. CC -!- PTM: Farnesylation mediates presynaptic targeting. CC {ECO:0000250|UniProtKB:Q8R1B5}. CC -!- SIMILARITY: Belongs to the complexin/synaphin family. {ECO:0000305}.
