Summary: Predicted to enable calmodulin binding activity and syntaxin-1 binding activity. Involved in negative regulation of synaptic plasticity and synaptic vesicle exocytosis. Acts upstream of or within chemical synaptic transmission. Is active in calyx of Held and parallel fiber to Purkinje cell synapse. Is expressed in several structures, including brain; limb interdigital region; molar; olfactory epithelium; and spinal cord mantle layer. Orthologous to human UNC13C (unc-13 homolog C).

Heterogeneous Presynaptic Distribution of Munc13 Isoforms at Retinal Synapses and Identification of an Unconventional Bipolar Cell Type with Dual Expression of Munc13 Isoforms: A Study Using Munc13-EXFP Knock-in Mice.
Title: Heterogeneous Presynaptic Distribution of Munc13 Isoforms at Retinal Synapses and Identification of an Unconventional Bipolar Cell Type with Dual Expression of Munc13 Isoforms: A Study Using Munc13-EXFP Knock-in Mice.
Munc13-3 regulates the density of Cav2.1 and Cav2.2 channels, alters the localization of Cav2.1, and is required for the development of tight, nanodomain coupling at parallel-fiber active zones.
Title: Munc13-3 Is Required for the Developmental Localization of Ca(2+) Channels to Active Zones and the Nanopositioning of Ca(v)2.1 Near Release Sensors.
We conclude that Munc13-3 is responsible for an additional step of molecular and/or positional "superpriming" that substantially increases the efficacy of Ca(2+)-triggered release.
Title: Munc13-3 superprimes synaptic vesicles at granule cell-to-basket cell synapses in the mouse cerebellum.
The composition of Munc13 isoforms in a neuron differentially controls its short-term synaptic plasticity characteristics.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
