The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 1 - 2 µg/ml. Predicted molecular weight: 193 kDa.
Use at an assay dependent dilution.
RelevanceFunction: Plays a role in vesicle maturation during exocytosis as a target of the diacylglycerol second messenger pathway. Involved in neurotransmitter release by acting in synaptic vesicle priming prior to vesicle fusion and participates in the activity-dependent refilling of readily releasable vesicle pool (RRP). Essential for synaptic vesicle maturation in most excitatory/glutamatergic but not inhibitory/GABA-mediated synapses (By similarity). Also involved in secretory granule priming in insulin secretion (By similarity). Interacts with FBXO45 (via SRY domain); leading to the degradation of UNC13A by the proteasome (By similarity). Plays a role in dendrite formation by melanocytes (PubMed:23999003).
Tissue specificity: Expressed in pancreatic islet cells (PubMed:12871971). Expressed in melanocytes (PubMed:23999003).
Similarity: Belongs to the unc-13 family.
Contains 3 C2 domains.
Contains 1 MHD1 (MUNC13 homology domain 1) domain.
Contains 1 MHD2 (MUNC13 homology domain 2) domain.
Contains 1 phorbol-ester/DAG-type zinc finger.
Domain: The C2 domains are not involved in calcium-dependent phospholipid binding.
The C-terminal region containing both MHD domains and the third C2 domain is required for synaptic vesicle priming activity.
Cellular localizationCytoplasm. Cell membrane; Peripheral membrane protein. Cell junction; synapse, presynaptic cell membrane. Note: Localized to the active zone of presynaptic density. Translocated to the plasma membrane as response to phorbol ester binding
