| Protein names | Recommended name: Phorbol ester/diacylglycerol-binding protein unc-13 Alternative name(s): Uncoordinated protein 13 | ||||
| Gene names |
| ||||
| Organism | Caenorhabditis elegans [Reference proteome] | ||||
| Taxonomic identifier | 6239 [NCBI] | ||||
| Taxonomic lineage | Eukaryota › Metazoa › Ecdysozoa › Nematoda › Chromadorea › Rhabditida › Rhabditoidea › Rhabditidae › Peloderinae › Caenorhabditis![]() |
Protein attributes
| Sequence length | 2155 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | May form part of a signal transduction pathway, transducing the signal from diacylglycerol to effector functions. One such function could be the release of neurotransmitter from neurons. |
| Domain | The phorbol ester binding activity is zinc and calcium-dependent. |
| Disruption phenotype | Worms exhibit diverse nervous system defects. Ref.1 |
| Sequence similarities | 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. |
