Genes affected

UNC13C (HGNC:23149): (unc-13 homolog C) Predicted to enable calmodulin binding activity and syntaxin-1 binding activity. Predicted to be involved in several processes, including glutamatergic synaptic transmission; regulated exocytosis; and synaptic vesicle maturation. Predicted to be located in presynaptic active zone. Predicted to be active in several cellular components, including axon terminus; parallel fiber to Purkinje cell synapse; and presynaptic active zone cytoplasmic component.
